The problem is

Two similar polygons have a scale factor of 3:5. The perimeter of the large polygon is 120 feet. Find the perimeter of the small polygon.

do not just tell me the answer, but please tell me how you got it as well. Thank you :)

**MathMate**, Saturday, February 4, 2012 at 8:15pmAssume the scale factor is s where s<1 since the second polygon is smaller.

If the scale factor s>1, that means the reciprocal should be use.

Let P=perimeter of the larger polygon, then the perimeter of the smaller polygon is

p=P*s

**Melanie**, Saturday, February 4, 2012 at 8:49pmDid you get 200 for this particular problem? cause that's what I got, which doesn't make sense to me because it's suppose to be less than 120 since it's the smaller polygon
