Rectangle A and B are similar. The ratio of rectangle B's width to rectangle A's width is 3:2. Rectangle A has a length of 24 inches and a width of 16 inches. What is the perimeter of rectangle B?

  • Math-II -

    perimeter of A = 2(24+16) = 80
    Since perimeter is a linear measurement

    x/80 = 3/2
    2x = 240
    x = 120
    The perimeter of rectangle B is 120

    check:
    120:80 = 12:8 = 3:2
