A town decides to build a playground using one of the existing walls beside an elementary school. What is the maximum area they can enclose using only 100ft of donated fence?

Letting L be the length against the building,
100 = L + 2W
so, L = 1002W
A = WL = W(1002W)
= 100W  2W^2
This has a max at W = 100/4 = 25
L = 50
A = 25*50 = 1250 ft^2
