Well, you know that in order to classify a shape as a rectangle all of the sides have to be congruent or 90 degrees. If you draw the diagonal of that rectangle, you come up with two right triangles. So you can use the Pythagorean theorem (a squared+b squared=c squared) to find out the diagonal.
Ex: If the length=4, and width=3, then diagonal=5, because 4 squared+3 squared=5 squared.
