If the ratio of the corresponding side lengths of two similar polygons is 5: 9, what is the ratio of their perimeters?
a.
5: 9
b.
10: 9
c.
25: 81
d.
10: 81

Step-by-step explanation:

Alright, lets get started.

The ratio of sides of polygon is 5:9, so

So, suppose sides of first polygon will be = 5a, 5b, 5c

So, the sides of second polygon will be = 9a, 9b 9c

Hence the perimeter of first polygon will be =

Similarly, the perimeter of second polygon =

ratios of both perimeters will be =

So, the ratios of perimeter  = 5:9 :    Answer

Hope it will help :)
