Find the area of the following trapezoids. Use the formula


AreaTrapezoid= 1
2
 (b1 + b2)h

(1) b1 = 3, b2 = 7, h = 6 (2) b1 = 4, b2 = 8, h = 5

(3) b1 = 11, b2 = 17, h = 9 (4) b1 = 12, b2 = 16, h = 15

(5) b1 = 22, b2 = 20, h = 16 (6) b1 = 14, b2 = 7, h = 8

(7) b1 = 13, b2 = 18, h = 8 (8) b1 = 15, b2 = 17, h = 8

(9) b1 = 15, b2 = 16, h = 8 (10) b1 = 30, b2 = 50, h = 20
