Afarmer 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)

The answer it´s: d) y=3x+1because it is a lineal funtion
