Question

The perimeter of. rectangle is twice as breadth . if perimeter is 72 m find its breadth​

Answer 1

Step-by-step explanation:

Let the breadth be a

Then length = 2(a) = 2a.

We know that, Perimeter of rectangle = 2( length + breadth).

Given perimeter = 72 m

=> 72m =2( a+2a)

=> 36=3a

=> a =12

Hence, Length is 2(12) = 24 m

Breadth is a =12 m
