Trapezoid Area Formula: Trapezoid Area = (Height / 2) * (Length of Top + Length of Bottom)

Trapezoid Area Definition The Trapezoid Area Calculator will calculate the area of a trapezoid if you enter in the height, the length of the top, and the length ofÂ the top of the trapezoid. A trapezoid is a geometric figure with 4 sides that has 2 parallel sides. In British English the trapezoid is called the trapezium. A parallelogram is thought of by some as being a special sort of trapezoid as it has 2 sets of sides that are parallel to each other (see our Parallelogram Area Calculator to calculate the area of a parallelogram).

How to Calculate Trapezoid Area Let's be honest - sometimes the best trapezoid area calculator is the one that is easy to use and doesn't require us to even know what the trapezoid area formula is in the first place! But if you want to know the exact formula for calculating trapezoid area then please check out the "Formula" box above.
