Question

Find a similarity ratio is the ratio of perimeter's for to regular pentagons with areas of 16 cm Square and 49 cm Square

Answer 1

4 : 7

Explanation:

Given 2 similar figures the if the ratio of perimeters = a : b

The the ratio of areas = a² : b²

Here

ratio of areas = 16 : 49 , then

ratio of perimeters =
`√(16)` :
`√(49)` = 4 : 7
