Question

The area of rectangle is 540 cm and its length is 36 cm. Find its width and perimeter.

Answer 1

$Area=length\times width$

$540=36\times width$

$width=\frac{540}{36}$

$width=15cm$

$perimeter=2\times \left(l+b\right)$

$=2\times \left(36+15\right)$

$=102cm$

We get, $perimeter=102cm.$
