Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! a) length = 38 feet and width = 22 feet
b) 38^2 + 22^2 = d^2
sqrt(38^2 + 22^2) = d
d = 43.9089968
c) Perimeter = (2*38) + (2*22) = 120 feet
cost = 7 * 120 = $840
therefore,
cost to decorate all sides of the pool with stone is $840
