Question

The area scale factor of two similar shapes is in ratio 9:25 find their linear scale factor​

Answer 1

3 : 5

Explanation:

Given 2 similar figures with linear scale factor = a : b , then

ratio of areas = a² : b²

Here ratio of areas = 9 : 25 , thus

linear ratio =
`√(9)` :
`√(25)` = 3 : 5
