To recall, a trapezoid, also referred to as a trapezium, is a quadrilateral with one pair of parallel sides and another pair of non-parallel sides.Like square and rectangle, trapezoid is also flat, therefore, it is 2D. You can use the right-triangle trick to find the area of a trapezoid. If we know the height and two base lengths then we can calculate the Area of a Trapezoid using the below formula: Area = (a+b)/2 * h. Where a and b are the two bases and h is the height of the Trapezoid. The formula for the area of a trapezoid is (base 1 + base 2) / 2 x height, as seen in the figure below: The calculation essentially relies on the fact a trapezoid's area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area. You could start by creating a parallelogram out of two trapezoids. Using the formula for finding the area of trapezoids. Related Topics: More Geometry Lessons In these lessons, we have compiled. Area of a trapezoid formula. Here if the height of the trapezoid is not given and legs of the trapezoid are given as l1 and l2 ,then by using pythagorean theorem we … In another words, Centroid of a Trapezoid is geometrically lies on the median.
