A trapezoid is a four sided shape with one pair of opposite parallel sides.
A trapezoid has some important dimensions: the length of the two bases and the height. It also has an area, which is the amount of space contained by a trapezoid.
This widget allows you to find the lengths of the two bases, heights and areas of trapezoids.
