Trapezoid area calculator trapezoid area calculator - step by step calculation, formula & solved example problem to find the area for the given values of parallel length a & b, & height h of trapezium in different measurement units between inches (in), feet (ft), meters (m), centimeters (cm) & millimeters (mm). In geometry, trapezium is a flat shape with four straight sides, one pair of opposite sides being parallel and the other pair not parallel. The claclulator, formula, solved example & step by step calculations may useful for users to understand how the input values are being used in trapezoid area calculations. Also this featured trapezium calculator uses the various conversion functions to find its area in SI or metric or US customary units.

## Trapezoid & its Formula

The following mathematical formula is used in this this calculator to find the area of a trapezoid for the given input value of parallel length a & b, & height h.

### Solved Example

The below solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.

Example Problem :
Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?

Solution :
The given values
bottom length a = 15 cm
top length b = 12 cm
height h = 10 cm

Step by step calculation
formula to find area = ((a + b)/2) h
substitute the values
= ((15 + 12)/2) x 9
= 121.5 cm2

The area of a trapezoid may required to be calculated in SI or metric or US customary unit systems, therefore this trapezium calculator is featured with major measurement units conversion function to find the output values in different customary units such as inches (in), feet (ft), meters (m), centimeters (cm) & millimeters (mm) by using this below conversion table.
