Question

The area of a regular octagon is 35 cm2. What is the area of a regular octagon with sides six times as long?


so do you times this by 6?

Answer 1

no, the area of similar figures is proportional to the square of their sides.
So....
V/35 = (6x)^2/x^2 = 36/1
V = 35(36)
= 1260 cm^2

Answer 2

56

Answer 3

I don't know what June is talking about, but the person above, reiny, is correct. You would not do that times six, because it's each individual side times six. V/35=6x squared/xsquared = 36/1
so 35*36=1260 cmsquared

Hope that makes sense. Sorry, I don't know why this whole response was so essay-like.
