Heather and Ben each have 20 ft of wood for framing their rectangular mural. Heather makes her frame 5 ft high. Ben makes his frame 2 ft high. Who's mural has the greater area? How much greater

Answer 1

heather 5 feet high with 20 feet total, that's 5 feet wide

that's 5x5 =25 ft^2 area

ben 2 feet high, that's 8 feet wide, area = 2x8 = 16 ft^2

heather's mural is 9 ft^2 more than ben's. 25-16= 9

the more like a square the larger the area with a fixed perimeter
