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?

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)
