Jared is using a 100 ft rope to set up a kite-shaped area for food vendors. He has started roping off the area as shown below and has one more stake to place. How can Jared use all of the rope to complete the kite shape? Explain.

A kite has two pairs of congruent adjacent sides and opposite sides that are not congruent. Jared has already created one pair of congruent adjacent sides. Since he has used 60 ft of rope, there are 40 ft remaining. This means that he will need 20 ft of rope for each of the other sides, or half of the remaining rope, in order to create another pair of congruent adjacent sides. Since this is a different length than 30 ft, the shape has opposite sides that are not congruent. is the correct answer
