What is the width of the border.

Question

A club swimming pool is 20 ft wide and 53 ft long. The club members want an exposed aggregate border in a strip of uniform width around the pool. They have enough material for 704ft^2 . How wide can the strip​ be.

Width, 27ft

Length, 52ft

Enough material 704ft^2

Answer 1

Draw and label a diagram

(27 + 2w))52 + 2w) is the size of the pool plus walkway

(27)(52) is the size of the pool

(27 + 2w))52 + 2w) is the size of the walk way

(27 + 2w))52 + 2w) = 704

Can you solve for w and answer?
