Calculate the area of a trapezoid

Area of a trapezoid

The trapeze is a type of geometric figure with four sides but which differs from the square or rectangle in that only two sides are parallel to each other.

Because of this, calculate the area of a trapezoid requires using a different formula than the usual multiplication of the base by the height. Luckily, our online calculator allows you to obtain the area of this geometric figure by simply entering the length of the smallest base, the longest base and the height.
