Question

Amy and zach each have 24 ft of fencing to make rectangular pen for their gsrdens.Amy make6 ft long zachmakes 8ftlong whose pen has greater area?How much greater

Answer 1

Amy by 4 feet.

Explanation:

Since one side of Amy's pen is 6 feet, to have a perimeter of 24, the other side also has to be 6 feet. This gives it an area of 6x6 = 36 feet. One side of Zach's pen is 8 feet, so to have a perimeter of 24 the other side has to be 4 feet and it has an area of 8x4 = 32. 36-32 = 4, making Amy's pen 4 feet greater in area.
