    12 inches 20 inches 36 inches

    Step-by-step explanation:

    ratio of 3:5:9

    Multiply each side by x

    3x: 5x: 9x

    Add the sides together to find the perimeter of 68

    3x+5x+9x = 68

    Combine like terms

    17x = 68

    Divide by 17

    17x/17 = 68/17

    x = 4

    The sides lengths are

    3*4: 5*4: 9*4

    12 : 20: 36
