Question

If the ratio of the area of two squares is 9:1 find the ratio of their perimeter

Answer 1

3:1

Explanation:

area is 2D while the perimeter is a length which is 1D. you can also about this in how the area is units squared while the perimeter is just units. so we need the square roote of 9 and 1, sqrt(9) = 3, sqrt(1) = 1. so the ratio of the perimeter is 3:1
