Q:
The perimeter of a rectangular sheet of metal is 120 feet, and the area is 800 square feet. The length and width of the rectangular sheet of metal are each multiplied by 6. What is the perimeter of the new sheet?
Accepted Solution
A:
800 = l(w)
120 = 2l + 2w
800 = 20(40)
120 = 2(40) + 2(20)
40(6)=240
20(6)=120
P=2(240) + 2(120)
P=480+240
P=720
Answer: Perimeter is 720ft
