Find the area of the following trapezoids. Use the formula


AreaTrapezoid= 1
2
 (b1 +b2)h

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



(3) b1 = 12, b2 = 18, h = 10 (4) b1 = 13, b2 = 17, h = 16



(5) b1 = 20, b2 = 18, h = 17 (6) b1 = 13, b2 = 8, h = 7



(7) b1 = 12, b2 = 13, h = 7 (8) b1 = 5, b2 = 7, h = 6



(9) b1 = 13, b2 = 14, h = 6 (10) b1 = 8, b2 = 9, h = 12



(11) b1 = 20, b2 = 12, h = 11 (12) b1 = 13, b2 = 21, h = 8



(13) b1 = 15, b2 = 17, h = 9 (14) b1 = 3, b2 = 7, h = 6



(15) b1 = 17, b2 = 18, h = 10 (16) b1 = 33, b2 = 11, h = 22
