Geometry
4.11 Area of a Trapezoid - I

Example:
The length of the parallel sides of a trapezoid are 10 cm and 7 cm. The distance between this is 4 cm. Find its area.

Solution:
Given that,
a = 10 cm, b = 7 cm and h = 5 cm.
The equation for the area of trapezoid is (A) = 1/2 * (a+b)*h.
= 1/2 * (10+7)*4
= 1/2 * 17 * 4
= 17 * 2
= 34 sq cm.
