Answer:
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
