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 + 2x
Longest Side: 3x
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?
