Question

b. A rectangular community pool has perimeterof 150 meters. The length of the pool is 50meters. What is the width?

Answer 1

The width of the pool is 25 meters.

Explanation:

Rectangle:

Has two dimensions: Length l and width w.

The perimeter is given by: P = 2l + 2w

In this question, we have that:

P = 150, l = 50. We have to find w. So

P = 2l + 2w

150 = 2*50 + 2w

2w + 100 = 150

2w = 150 - 100

2w = 50

w = 50/2

w = 25

The width of the pool is 25 meters.
