Question 1168319: 1. Ken has a pool 20 feet by 24 feet. He wants to put grass in a strip of uniform width around the pool. He has enough grass strip of 192 𝑓𝑡2 . How wide will the strip be? Answer by ikleyn(52778) (Show Source):
(1) 20*24 = 480 ft^2 is the area of the pool.
(2) 480 + 192 = 672 ft^2 is the area of the pool and the strip around the pool.
(3) Now I want to present the number 672 as the product of two integer factors with the difference 4 (same as the difference 24-20) between them.
This presentation is 672 = 24*28.
(4) Therefore, = = 2 ft is the answer to the given problem.
