The ratio of the areas of two similar polygons is 16:25. If the perimeter of the first polygon is 20 cm, what is the perimeter of the second polygon?

Question

jim_thompson5910 · Answer

If 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)

jim_thompson5910 · Answer

It turns out that the perimeters form the same ratio as the sides since the perimeter is simply the sum of all the sides

jim_thompson5910 · Answer

we 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
