The definition of a trapezoid is a shape with four sides, only two of which are parallel. An example of a trapezoid is the base of a pyramid when the top is flat and there is not a point. 1  a plane figure with four sides, only two of which are parallel.  Brit. trapezium (sense )
Save. gionnixxx/iStock/Getty Images. A trapezoid is a quadrilateral -- a four sided shape -- with two parallel sides, called bases, of unequal length. You can find the area of a trapezoid using the lengths of these two sides, and the distance between the two sides, called the height.If you don't know a trapezoid's height, solve for it using the Pythagorean Theorem and length of the trapezoid's diagonals, the two sides that connect its bases.rea, A, is given by the lengths of the two bases, b1 and b2, divided by 2 and multiplied by the trapezoid's height, h, as follows: A = (b1 + b2) / 2 x h. Take a trapezoid whose bases are 4 and 6 inches long and which is 2 inches high.
