Area of trapezoids

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases. The nonparallel sides are called legs.

Area of a trapezoid

 $Area=\frac{B+b}{2}\cdot\;h\;$, where B and b are the lengths of the two bases and h is the height of the trapezoid

Find the area.
 $Area=\frac{B+b}{2}\cdot\;h\;$ $Area=\frac{16+12}{2}\cdot\;5\;$ A=80 units2

What is the area B=6, b=2, and h=1?
