The area of any trapezoid with base side lengths "b1" and "b2" and height "h" is given by the formula A = h(b1 + b2)/2. The base sides are the trapezoid's two parallel sides. The trapezoid's height is the length of a per... More »

Calculate the area of a trapezoid by identifying the length of the two parallel bases and the height of the polygon. Then, use the formula A = a + b/2 (h), where "a" and "b" are the two parallel base lengths and "h" refe... More »

A trapezoid is a four-sided shape that has only two parallel sides. Most quadrilaterals have two pairs of parallel sides for four sides total, such as squares, rectangles, rhombuses and parallelograms. More »

A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides. A quadrilateral is a geometric shape that has four sides. Some specialized types of trapezoid are the parallelogram and the isos... More »
