Also I need help with finding the area of a octagon with a radius of 20in.

Can someone also double check if I did these ratio right?

A similar pair of triangles the small triangle has a area of 12 cm and the large has an area of 48 cm.

Ratio of areas = 1:4

Scale factor = 4 in terms of two-dimensional areas

Ratio of perimeter = 1:4 perimeter is one-dimensional

Did I do that one right?

Thanks for your help.
