3.28 Area of Trapezoid

Example:
The length of the parallel sides of a trapezoid are 15 cm. and 22 cm. The distance between this is 4.4 cm. Find its area.
Solution:
Area of Trapezoid (A) = 1/2 * h(a+b)
Given that,
a = 15 cm. , b = 22 cm. and h = 4.4 cm.
Therefore, A = 1/2 * 4.4 (15+22)
A = 2.2 * (37)
A = 81.4 Sq. cm.
