Question

How do the perimeters of the rectanglescompare?Length of the original rectangle: 18 inWidth of the original rectangle: 12 inLength of the scaled rectangle: 90 inWidth of the scaled rectangle: 60 inA. The scaled rectangle's perimeter is 5 times longerthan the original rectangle's perimeter.B. The scaled rectangle's perimeter is 8 times longerthan the original rectangle's perimeter.C. The scaled rectangle's perimeter is 1/5 as long asthe original rectangle's perimeter.D. The scaled rectangle's perimeter is 25 times longerthan the original rectangle's perimeter.

Answer 1

Perimeter of the original rectangle = 2*length + 2*width = 2*18 + 2*12 = 60 in

Perimeter of the scaled rectangle = 2*length + 2*width = 2*90 + 2*60 = 300 in

300/60 = 5, then the scaled rectangle's perimeter is 5 times longer than the original rectangle's perimeter
