Question

How many rectangles can be drawn given that the perimeter of each rectangle is 22cm. In each case find the rectangle. (Take leagth and breadth and whole numbers)​

Answer 1

Answer:

according to the question we can Draw infinity many rectangle whose perimeter should be 22cm.

Answer 2

Answer:

10 rectangles we can draw whose parameter is 22 cm

Step-by-step explanation:

As we have given in the question that the perimeter is 22 cm, Now we have to find the number of rectangles that can be made of 22 cm perimeter but the length and breadth should be in whole numbers

As we know that perimeter=$2[l+b]$=22 cm

$l+b=11 cm$

Therefore the sum of length and breadth should be 11 cm, We have to make pairs in how many conditions their sum must be 11 cm

So the following pairs are:

> 1,10

>10,1

>2,9

>9,2

>3,8

>8,3

>4,7

>7,4

>6,5

>5,6

Here are the total pairs as [l,b] in which 22 cm rectangle can be made
