Area of Trapezoids Tutorial 13c

Trapezoids In a trapezoid, the parallel sides are the bases (b1 & b2). The nonparallel sides are the legs. The height h is the perpendicular distance between the two parallel bases. b1 b2 h leg leg

Area of a Trapezoid The area of a trapezoid is half the product of the height and the sum of the lengths of the bases. b1 h b2

Example Find the area of the following trapezoid: 21 cm 16 cm 38 cm

Trapezoids Example #2 A = ½•6(6 + 10) A = ½•3(3.2 + 4.4) = ½•6(16) 2. A = ½•6(6 + 10) A = ½•3(3.2 + 4.4) = ½•6(16) = ½•3(7.6) = 48 cm2 = 11.4 cm2
