Question

How do I find the ratio of this? It makes no sense to me

Answer 1

`(169)/(289)`

Explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus

ratio of areas = 13² : 17² = 169 : 289 =
`(169)/(289)`
