The perimeter of this rectangular portion needs to be 14 yards and the diagonal is 5 yards. Can you help Mike determine the length and width of this new portion? Mike requested that you show him how you arrive at the answers.

The perimeter is the distance around the rectangle. Let's try a width of 3 yards and a length of 4 yards.
Then use the Pythagorean theorem to see if the diagonal is 5 yards.
