A kite has vertices at (2, 4), (5, 4), (5, 1), and (0, –1).What is the approximate perimeter of the kite? Round to the nearest tenth.

The side lengths in order are 3 units, 3 units, √29 units, and √29 units. The two diagonal lengths are each about 5.4 units, so the perimeter is about 3 + 3 + 5.4 + 5.4 = 16.8 units. The correct choice is C, 16.8 units.
