Area of a Trapezoid Calculator
Calculate the area of a trapezoid with given lengths of sides and height in selected units.
How to use this calculator?
- Enter the Side length (a) in the selected unit.
- Enter the Side length (b) in the selected unit.
- Enter the Height (h) in the selected unit.
- See the calculated Area of a Trapezoid in the Result section.
How to calculate Area of a Trapezoid?Add the lengths of sides a and b, and then divide the result by 2. Take this number and multiply it by the height of the trapezoid (h).
Area of a Trapezoid = (a + b) / 2 * h
- a - Side Length (a)
- b - Side Length (b)
- h - Height (h)
Area = (a + b) / 2 * h
Area = (7 cm + 10 cm) / 2 * 8 cm
Area = 17 cm / 2 * 8 cm
Area = 8.5 cm * 8 cm
Area = 8.5 cm * 8 cm = 68 cm²
