# Trapezoid Height Calculator

Calculating the height of trapezoid becomes easier when we know the base lengths and area of the typical trapezoid. Here is an example to understand it better.

## Calculating Height of a Trapezoid

Example: A trapezoid has a base lengths of 8cm and 12cm. Its area found to be 40cm2. Find the trapezoid height.
Solution:
Given:
A = 40 cm2
b1 = 8cm
b2 = 12cm
We know the formula to find area of trapezoid (A) = 1/2 (b1 + b2) h
40 = 1/2 x (8 + 12) x h
40 = 1/2 x (20) x h
40 = 10 x h
40/10 = h
h = 4 cm
Therefore, the height of the given trapezoid is 4 cm.

In the below online trapezoid height calculator, enter the values in the respective input boxes and click calculate to find the output.

 Area of Trapezoid (A): [cm2] Base 1 Length (B1): [cm] Base 2 Length (B2): [cm] Height of Trapezoid: [cm]
