11-2 Area of Trapezoids, Rhombi and Kites Vocab: Height of a trapezoid: The perpendicular distance between bases Formulas: Area of a trapezoid: ½ height(base 1 + base 2) Area of a rhombus or kite: ½ diagonal 1 x diagonal 2

Area of Trapezoids Ex 1: Find the area Ex 2: Find the area

Area of Rhombi and Kites Ex 3: Find the area Ex 4: Find the area

Word Problems Ex 5: 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? Ex 6: 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?
