Best ResponseYou've already chosen the best response.3If the ratio of the two areas is 16:25, then the ratio of the sides is 4:5 (you take the square root of each component)

Best ResponseYou've already chosen the best response.3It turns out that the perimeters form the same ratio as the sides since the perimeter is simply the sum of all the sides

Best ResponseYou've already chosen the best response.3we know that the ratio of the perimeters is 4:5, so 4/5 = 20/x Solve this for x to find the perimeter of the second polygon
