Two similarity ratio of two similar polygons is 3: 1. find the ratio of their perimeters a)3: 1 b)6: 1 c)9: 1 d)27: 1

Here similarity ratio of two similar polygons given. Similarity ratio means ratio of the corresponding length of two similar polygons.

That means here the ratio of the corresponding lengths of two similar polygons is 3:1.

We have to find the ratio of the perimeters of them.

Perimeter is also a linear measurement. So the ratio will be same as for the lengths of the polygons.

Therefore, the ratio of the perimeter of the polygons = 3:1

So, we have got the required answer.
