Examples A trapezoid has base lengths of 6 and 15 centimeters with an area of 136.5 square- centimeters. What is the height of the trapezoid? One diagonal of a kite is four times as long as the other diagonal. If the area of the kite is 72 square meters, what are the lengths of the diagonals?

Practice A trapezoid has base lengths of 19.5 and 24.5 centimeters with an area of 154 cm2.What is the height of the trapezoid? One diagonal of a kite is twice as long as the other diagonal. If the area of the kite is 400 square meters, what are the lengths of the diagonals?
