Question 4 of 5
Trapezoid

A trapezoid is a quadrilateral with one set of parallel sides. The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height. In this diagram, that becomes ½(b + d)(h).

6

The dimensions of this trapezoid are a = 4, b = 4, c = 5, d = 2, and h = 2. What is the area?
