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

Answer:

4 : 7

Step-by-step 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 = $\sqrt{16}$ : $\sqrt{49}$ = 4 : 7
