The ratio of the areas of two squares is 4 to 9, what is the ratio of their perimeter in the same order?

1 answer:

7 0

A square with area 4 has side lengths of 2 since s^2 = area
A square with area 9 has side lengths of 3 since s^2 = area
The perimeter of a square with side length 2 is 4*2
The perimeter of a square with side length 3 is 4*3
So ratio of the perimeters is 2:3
