Trapezoid Calculator
Find trapezoid area from two parallel sides and height.
📐 Trapezoid area = average of parallel sides × height.
What Is This Tool?
A trapezoid has two parallel sides (the bases). This calculator finds the area from the lengths of those sides and the perpendicular height.
The Formula
Area = ((a + b) / 2) × h, where a and b are the parallel sides and h is the perpendicular distance between them.
Real-World Uses
- Irregular lots in real estate
- Trapezoidal windows and architectural features
- Calculating volumes of ditches and embankments
- Graphics and design work
Frequently Asked Questions
What if my sides aren't parallel?
Then it's not a trapezoid — it's an irregular quadrilateral. You'll need more measurements or different formulas (like dividing into triangles).
