Question 478222: A rectangular swimming pool measures 20 feet by 40 feet. A walk of uniform width surrounds it. The total area of the pool and the walk is 1500 ft^2. Find the width of the walk. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! x = width of walk
-----------------
(x+20)*(x+40) = 1500
(x-10)*(x+70) = 0
x = -70 (makes no sense)
x = 10 feet works
