    Perimeter is 128 in, length of each side is 16 in

    Step-by-step explanation:

    2 : 4 = 1 : 2

    Perimeter is the sum of sides.

    Ratio of the perimeters is the same ratio as of the sides.

    side A : side B = 1 : 2

    Perimeter A : Perimeter B = 1 : 2

    Perimeter of Octagon B is 2*64 = 128 in

    With each side equal to 128/8 = 16 in
