Question

The area of a rectangle having length $22$ cm is $440$ cm${}^2$. Then find the perimeter of the rectangle?

Answer 1

Given the area of a rectangle having length $22$ cm is $440$.

Then breadth of the rectangle will be $\frac{440}{22}=20$ cm.

So length is $22$ cm and breadth is $20$ cm.

Then perimeter of the rectangle is

$=2(22+20)$

$=2\times 42$

$=84$ cm.

So the perimeter is $84$ cm.
