# Area of a trapezoid

## Description

Trapezoid is a convex quadrilateral with only one pair of parallel sides. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides.The height (or altitude) is the perpendicular distance between the bases. The area of a trapezoid can be calculated by the length of the bases and the length of the height of the trapezoid.
