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).
The dimensions of this trapezoid are a = 5, b = 5, c = 7, d = 5, and h = 3. What is the area?
