Question

Find the similarity ratio and the ratio of perimeters for two regular octagons with areas of 18 in2 and50 in2

Answer 1

Answer:

3:5 (or 3/5)

Step-by-step explanation:

The ratio of area is equal to (ratio of perimeters)^2

That means...

(18:50) = (a:b)^2

This simplifies to:

(9:25) = (a:b)^2

Which means...

3:5 = a:b
