To quickly find the perimeter of a trapezoid, follow these steps: Or you can alternatively use the area of a trapezoid calculator, which will automatically find the area and perimeter of the trapezoid for you. The formula for the area of a trapezoid is expressed as, where (A) is the area of a trapezoid, 'a' and 'b' are the bases (parallel sides), and 'h' is the height (the perpendicular distance between a and b). The area of a trapezoidal prism is the sum of the surfaces of the prism. We use cookies to make wikiHow great. In the specific case of a right trapezoid, one of the two remaining sides, ccc from the figure, is perpendicular to the parallel sides aaa and bbb, creating 90 angles (right angles) between them. It is represented in terms of square units. Taking a trapezoid of bases 'a' and 'b' and height 'h', let us prove the formula. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
