Question

two similar polygons have perimeters of 28 and 40;
what is the ratio of their areas?
what is the ratio of their volumes?

thank you :)

Answer 1

28/40 = 7/10
therefore, the ratio of their areas = (7/10)^2 = 49 : 100
and the ratio of their volumes = (7/10)^3 = 343 : 1000

Answer 2

wouldnt they all just simplify to 7/10 though?

Answer 3

never mind, haha thank you!

Answer 4

you're welcome ;)
