Question

A farmer has 80 feet of fencing to fence four sides of a rectangular garden what is the greatest area of garden that the farmer can fence?

Answer 1

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)
