Height of Trapezoid Calculator

Height of trapezoid calculator calculates the height of a trapezoid by knowing its area and two base lengths.

Trapezoid Height Formula

The trapezoid height formula is

H = 2 x A / (a + b)

where

a = base length
b = base length
A = area

Example

For example, if one of the base lengths is 10, the other base length is 7, and the area is 40.

The height is calculated as

H = 2 x 40 / (10 + 7)

H = 4.71
