Write an equation to represent this problem and find the unknown side lengths. Use the 5-D Process to help you organize your thinking and to define your variables, if you need to do so. Remember to define your variable.

A trapezoid has a perimeter of

Perimeter is the sum of the lengths of all the sides.

Create an expression comparing each side with the shortest side, represented by .

Two Shortest Sides:

Third Side:

Fourth Side:

Perimeter:

Shortest Sides:

What are the other side lengths?

Be sure to know how to get this length and the other lengths.
