Two corresponding sides of similar polygons have the ratio 5:4. The perimeter of the smaller figure is 40, what is the perimeter of the larger figure...I need help trying to figure this out...and the steps!

"Similar" is a vague term. If the polygons are congruent (the same shape), then

5:4::x:40 or

5/4 = x/40

Solve for x.
