Answer: a rectangle is a quadrilateral having opposing sides parallel and four right angles

Area of rectangle = length * width

Step-by-step explanation: Given Area of rectangle = 220 square foot

1 side of the fence = 220/4 = 55 feet

If 3 sides of the fence cost $3

Total cost for 3 sides of the fence = ( 55 + 55 + 55) * 3 = 165 * 3 = $495

Total cos for the 4th side = 55 * 13 = $715

It is more economical to construct the fence with materials that cost $3.
