Question 568196: a pool is to be 30 feet wide and 90 feet long. A walkway is to be built around the entire pool. if the combined area cannot exceed 4000 square feet what are the possible widths of the walkway?
You can put this solution on YOUR website! Area of pool = 30* 90 = 2700 ft^2 ( rectangle)
Area of pool + walkway = 4000 ft^2
area of walkway = 1300 ft^2
let the width of walk way be x
x= 5 m
The width has to be less than 5 m
