since the lengths are 3:8,
perimeter, also a length, is 3:8
area = length*length = 3^2:8^2 = 9:64
The ratio of the sides of two squares is 3:8. Find the ratio of the perimeters of the two squares. Find the ratio of the areas of the two squares.

thank you Steve
Let the side of square be 3x and 5x
So Area =9x
2
and 25x
2
Ratio =
25x
2
9x
2
=9:25
So Area =9x
2
and 25x
2
Ratio =
25x
2
9x
2
=9:25
