when the sides are as equal to each other as possible, then that is max area
solve assumg that all sides are equal legnths
4 sides to a rectangle
4 times side=80
divide both sidse by 4
side=20
each side is 20
area=side times side
aera=20 times 20
area=400
answer is 400ft^2 of area
(note, a square is a rectangle, but not all rectangles are squares)
