9-96.

Create a variable expression for perimeter to represent this problem with the shortest side defined by *x*.

How do the other sides relate to the shortest side, or *x*?

Shortest Side: *x*

Medium side: 10 + 2*x*

Longest Side: 3*x*

Add the lengths of the sides and set equal to the perimeter in order to solve for *x*.

Shortest Side: 22 cm

What are the lengths of the other sides?
