Question

The perimeter of a rectangular pool is $56\ m$.Ifthelengthofthepoolis$16\ m$, then find its width.

Answer 1

In this question the perimeter and length of the rectangular pool are given we have to find width of the pool.

( diagram )

The perimeter $P$ of a rectangular is given by formula $P=2l+2w$ where $l$ is the length and $w$ is width of rectangle.

Given that perimeter is $56$ meters and length's $16$ meters. Substituting values in formula,

$\Rightarrow 56=32+2w$

subtract $32$ from both sides -

$\Rightarrow 24=2w$

$w=12$

width of rectangular pool is $12$ meters.

Hence, the answer is $12.$
