Question

the perimeter of a rectangle is 72 m.its breadth is 10 m less than its length.find the dimensions

Answer 1

Hey...

Here’s ur answer....

Given that the perimeter is 72 m..

Let us assume that length = x and breadth = x - 10....

So, 2 * ( l + b ) = 72....

So..., x - 10 + x = 72/2... = 36...

So, 2x = 36 + 10..

x = 46/2... = 23...

Therefore length = 23 m and breadth = x - 10 which is 23 - 10 = 13 m...

Hope it helps... :)

Answer 2

HELLO MATE HERE IS YOUR ANSWER....

LET THE LENGTH BE Xm
AND THE BREADTH BE (X-10)m
GIVEN PERIMETER OF THE RECTANGLE=72m
THAT IS,2(X+X-10)=72m
»2(2X-10)m=72m
»(2X-10)m=72/2m
»(2X-10)m=36m
»2X=(36+10)m
»2X=46m
»X=46/2m
»X=23m

SINCE X=23 THAT IS LENGTH = 23 m
BREADTH= (23-10)m=13m
