The lengths of the parallel sides are also called as the base lengths of the trapezoid.

Hence, base lengths ‘a’ and ‘b’ are 5m and 9m.

Given height of the trapezoid, h = 6m

Area, A = 1/2 * (a + b) * h= 1/2* (5m + 9m)* 6m = 1/2 * 14m * 6m = 42m

height of the trapezoid is 10m.

Given are the base lengths of the trapezoid, ‘a’ and ‘b’ are 12m and 7m.

Given height of the trapezoid, h = 10m

Area of the trapezoid, A = 1/2 * (Sum of base lengths) * height

Area, A = 1/2* (12m + 7m)* 10m= 1/2 * 19m * 10m = 95m
