Question 241157
"You are told to build a rectangular fence along side a building.
 You have only 80 feet of fencing.
 The company wants the maximum amount of area enclosed.
 Find the dimensions that will lead to the most area" 
:
Along side a building, only 3 sides required, the equation:
L + 2W = 80
L = (80-2W)
:
Area = L * W
A = (80-2W)*W
A = -2W^2 + 80W
Find the axis of symmetry for max area
