fs there ony it is colled the 'perimeter'. term used for Perimeler is the sum of the lenqths of oll the sides of a frgure. Perimeter of a Rectangle The perimeter of a rectangle can be found out by adding the lengths of its four sides. Perimeter of the rectangle ABCD = AB + BC + CD + DA Exa mple Find the perimeter of the rectangular <-25 cm--\"-----> photo frame. <_25 cm_--_--> Perimeter of the photo frame = 25 cm + 20 cm + 25 cm + 20 cm = 90 cm Thus, the perimeter of the photo frame is 90 cm. Example 2: What should be the length ofthe fence around a field of length 10 m and breadth 8 m? Length of the fence would be the same as the E perimeter of the field. Perimeter= 10 m + 8 m + 10 m + 8 m = 36 m Thus, the length of the fence should be 36 m. 10m Perimeter of a Square its sides. The perimeter of a square is the sum of the lengths of Dc Perimeter of the square ABCD +BC+CD+DA

t) Example l\": Find the perimeter of a square of side 12 cm. Perimeter of the squarc = 72 cm + 12 cm+12 cm + l-2 cm =48cm Thus, the perimeter of the square is 48 cm. Example 2: Find the perimeter of a square field of side 22 m' 22m Perimeter of the square field =22m+22m+22m+22 m = 88 m Thus, the perimeter of the square field is 88 m' Can you find the perimeter of the following figure? lf the figure is not a regular rectangle or a square, you can measure the Iengths of all its sides and add these to get its perimeter. 4cm E (o E c{ 8cm Perimeter=8cm+6cm+ 4cm+3cm+2Cmr 1cm + 2 cm + 2 Cm =28cm Thus, the perimeter of the given figure is 28 cm. Perimeter of Other Figures We now know that the perimeter of a figure can be found out by adding the lengths of all its sides. so, we can find the perimeter of other figures such as a triangle or a polygon.

Example l-: Find the perimeter of the triangle. 5cm Perimeter = 5 cm + 10 cm + 8 cm 8cm =23cm 22 cm Thus, the perimeter of the triangle is 23 cm. Example 2: Find the perimeter ofthe given polygon. Perimeter= 7 cm + 22 cm +8 cm + 16 cm =53cm Thus, the perimeter of the polygon is 53 cm. Perimeter of Curved Figures How do we find the perimeter of a circular plate? To find the perimetet use a string to wrap around the outer edge of the plate. When you reach the starting point, mark the position on the string, Plate remove it and measure it with the help of a ruler. The length of the string used will give the perimeter of the plate. Suppose the length of the string used is 50 cm. Then the perimeter of the plate will also De 5U Cm. 1. Find the perimeter ofthe following figures. One has been done for you. a. 10m D' L8m 10m 44m

I Cffi, Area The amount of surface occupied by a shape is called its area. To find the area of a figure, place it on a graph paper. Trace the shape on the graph paper. Count the number of squares that are covered. The number of unit squares inside the traced figure gives the area of the shape' The unit for area is square metres or square centimetres. It is also written as 'sq. m' or 'sq. cm'. The given figure ABCD occupies 9 squares. lf each small square is of area 1 then the area of ABCD is 9 sq. cm. Area of Regular ShaPes Look at this birthday greeting card. Let us place it on a square-ruled sheet. We find that it occupies 40 squares. Thus, the area of the card is equal to the area of 40 squares. lfthe area of each small square is 1 sq. cm, the area of the card is 40 sq. cm. Example 1: What is the area of the shape shown on the right if each small square has an area of 1 sq. cm? To find the area of the shape, count the number of squares occupied by it. It occupies 25 squares on the sheet and each square has an area of 1 sq. cm. Hence, its area is 25 sq. cm. Example 2: Find the area of the given shape, J/rtz z ,+3 if the area of each square is 1 sq. cm Count the number of squares occupied by the shaPe. lt occuPies 50 squares and each square has an area of 1sq. cm.

Finding the Area of Other Polygons How to find the area of a polygon, which occupies not only full squares but half squares also, where the area of each square is 1 sq. cm? To find the area, follow these rules. . consider the area of a full square as 1 sq. cm. . consider the area of a half squar\" u, 1rq. .rn. Example: Find the area ofthe figure given alongside. Count the number of full squares occupied by this figure. The number of full squares is 6. Count the number of half squares. The number of half squares is 10. Area of 6 full squares = 6 sq. cm Area of 10 half squsrs5 = 19 x 1 sq. cm = 5 sq. cm 2 Total area covered by 6 full squares and L0 half squares is LL sq. cm. Thus, the area of the given figure is l.L sq. cm. Area of lrregular Shapes To find the area of irregular shapes, follow the given rules. . Area of a full square is to be taken as l- sq. cm. . Area of a small square, which is half or more than hall is to be taken as 1 sq. cm. . Area of a small square, which is less than halt is not to be considered. Example: Find the area of the shape, if the area of each small square is 1sq. cm. Count the number of full squares covered by the shape. The number of full squares is 20. Count the number of squares which are covered half or more than half (.). The number of such squares is 11. Total area = 20 + L1 = 31 sq. cm approximately lgnore the squares which are covered by less tha n half. Thus, the area of the shape is 31 sq. cm approximately. Ft lt48Lr. -rwJgL-,---

Reading Time to the Exact Minute So far you have been reading time correct to five minutes. Now let us learn to read time to the exact minute. When the hour hand moves from one number to the other, we say one hour has passed. But when the minute hand moves from one number to the other, we say five minutes have passed. Small divisions between any two consecutive numbers represent a minute. When the minute hand moves from one small division to the next small divisron. we sav one minute has passed. When the minute hand completes one fullcircle covering all 60 small divisions, that is, 60 minutes, we say that one hour has passed. What is the time shown on the clock? The hour hand is between 1 and 2 and the minute hand is at 28. Thus, the time is 1:28 or 28 minutes past L.

2 What is the time shown on this clock? 9 The hour hand is between 11 and 12. The minute hand is at the .'9a , small division just before 5. Thus, the time is 11:24 or 24 minutes past 11. 1.

Finding Number of Days A year has 365 days. January, March, May, July, August, October and December have 31 days. The rest of the months have 30 days except February which can have 28 or 29 days' To find the number of days that have elapsed between two incidents, you need to find the difference between both the numbers. Example 1: How many days have elapsed between 12th January and Lst February? (12th January is not included). Number of days in January = 31- 12 = 19 days (Since January has 31 days) Number of days in February = 1 day Total number of days = 19 + L = 20 days Example 2: Nina's father left for Kolkata on 18th July and returned on 25th July. How many days did he stay there? (18th July and 25th July are not included). He staved in Kolkata from 19th July to 24th July. Thus, the number of days he stayed there = 25 - 19 = 6 days Example 3: How many days are there between 5th June and 21st October? (5th June is not included). Number of days left in June = 30 - 5 = 25 days (since June has 30 days) Number of days in July = 31 6\"ut Number of daYs in August = 31 days Number of days in September = 30 days Number of davs in October = 21 days Total number of davs = 25 + 31 + 31 + 30 + 21 = 138 days Occurrence of a Leap Year The Earth actually takes 3651 days to go around the sun. .bG-----Ft But, we consider that a normal year consists of 365 days. I l58lf

However, every fourth year we get 1 day extra (4 quarters put together). That extra 1 day is included in February and that particular year is called a leap year. A leap year has 366 days with 29 days in February. How do we know whether a given year is a leap year? lf the year is divisible by 4, then it is a leap year. For example, 2004, 1996 and 1980 are leap years since all are divisible by 4. But 2001, 1995 and 2011 are not leap Vears.

Let us try to understand how Rohan is able to save money, by learning the operations on monev. Adding Money Always add rupees with rupees and paise with paise. Example 1: Add { 158.50 and < 142.75. 158 50 Here,50p+75p=125p L42 7 5 125 p can be written as 100 p + 25 p. 3 01 2s Write 25 p in the paise column and carry over L00 p or < 1to the rupees column. Thus, the sum is { 301.25. Example 2: Arya bought a luggage bag for I 2187.50 and a school bag for { 445.00. Find the total amount spent. Cost of the luggage bag 2187 50 Cost of the school bag 445 00 Total cost 2632 50 Thus, he spent a total of < 2632.50 on buying the bags. Subtracting Money Subtract rupees from rupees and paise from paise. lf it is not possible to subtract in the paise column, borrow { 1or 100 p from the rupees column and then subtract.

Making a Bill A bill is a written statement showing the money that we owe to someone for goods or services that we receive at the time we buy anything from a shop. The shopkeeper prepares a list of the things bought, their prices and the total amount to be paid. This list is called a bill. Mr Rathore bought some items from a grocery shop and given below is the bill that the shopkeeoer has made.

Pie Chart Data can also be represented pictorially with the help of pie charts. A pie chart is a circular chart representing the relationship between a whole and its parts. In a pie chart, a circle is divided into parts according to the number of data items. Example 1: Nidhi has 12 course books,6 self-help books,3 story books and 3 comic books. Represent the data in a pie chart. Add the number of books Nidhi has, to get whole number of books, that is L2+6+3+3=24. So, the complete circle represents allthe 24 books. Out of 24 books, 12 are course books. Comic books ]= {nati of the circte) Story books Course books -1? out of 24 books, 6 are self-help books. f-9 = {one-fourth of the circle) Se lf- h e lp /,/ Out of 24 books, 3 are story books. oooKs -l f= {one-eishth of the circle) Out of 24 books, 3 are comic books. f-a = {one-eiehth of the circle) We can draw the pie chart based on the above data as shown. Example 2: The pie chart shows the favourite sports of a group of children. Answer the following questions. Cricket a. What fraction of the children's favourite sport is footba ll? one-fourth of the children's favourite sport is football. b. Which two sports are equally liked by Basketball Football Volleyball the children? Basketball and volleyball are equally liked by the children. c. lfthetotal numberof children is 160, then how many children like cricket? It can be clea rly seen from the pie chart that half of the group of children likes cricket. lf there are 160 children, then the number of children whose tavourite sport is cricket is equal to 190 = ao.

t4 To handle problems effectively, students must be taught how to read mathematics well. The strategy to be followed differs from problem to problem. ln general, any problem solving method can be explained as follows: Step 1: Understand the problem i. Read the whole problem slowly. ii. Rephrase the question in your own simple language. iii. Find out what is given. iv. Find out what is being asked. v. ldentify the relevant information. Devise a suitable strategy i. Draw a picture or a diagram with the given information. Or i Make an organised list of what is given. Or Make a table of information given. ii. Decide how to use the above strategy. i Carry out your plan i Do all the calculations methodically and carefully. h.....

Step 4: Check your answer by a suitable method. We will now solve a problem together with the suggested strategy to find the solution. Draw a Picture/Diagram/Flowchart Problem Eight teams are playing in a tournament. The season's champion will be decided bv removing the team out of the tournament if it loses a match. How manv matches will the season's champion team have to play? A simple way to approach the problem is to draw a diagram/flowchart. TI,f2, . . ., T8 represent the eight teams. W7 is the Champion W1, W2, . . . W4 represent the winners in each match. t'--)* The champion team will have to play 3 T8 matches. Solve a similar problem with 12 teams. Problem The lengths of three chains are 5 cm, 7 cm and 13 cm. How can vou use these chains to measure a length of LL cm? Drawing pictures of va rious placements of the chains will help Vou to arrive at the solution. Arrangement 1: lf.f-i- 5 66 -*l f S ., |t- lcm x 13 cm

Arrangement 2: l-S cm -------*1.-r.r.-------------- l -J=-=---J--a- @x cm Ftrrffi{ffi€-Arrangement 3: l<-7cm 11 cm --------+l CrTt-l<-Scm-l The last arrangement gives you the solution to the problem. How can you use four rods of lengths 2 cm, 5 cm, 7 cm and 9 cm to measure a length of 1 cm? Make an Organised List Another useful problem solving strategy is organising information into a methodicar list. A list may help you account for all possibilities and avoid repetitions Problem How many different secret codes can be made out of 0, 5 and A? Repetition is not allowed. Let us make a list. I code startinq- with o (\\A 05A, 0A5 You have a pair of brown pants, a pair / _Code sta rting with 5 ,zo 50A,5A0 of black pants, a white shirt, a yellow A A05, A50 shirt and a red tie. How many different combinations can you make with a pair - \\s] coce startinq with n .. of pants, a shirt and a tie? Thus, 6 different secret codes can be made without repetition. Make a Table When a problem involves more than one characteristjc, an effective problem solving strategy is organising the data into a table. 0'ii-Tat -----
