📐 Area of a Trapezoid Calculator – Find Area Using Base & Height

Use this free Area of a Trapezoid Calculator to quickly find the area of any trapezoid using the base lengths and height. Whether you’re studying geometry, working on homework, or double-checking your math, this tool gives you accurate results in seconds.












⚙️ How to Use This Area of a Trapezoid Calculator

To use this calculator:

  1. Enter the lengths of both bases.
  2. Enter the height (the perpendicular distance between the bases).
  3. Click the "Calculate Area" button to see the result instantly.

📏 What Is the Area of a Trapezoid?

The area of a trapezoid is the amount of space inside its four sides. A trapezoid has two parallel sides (called bases) and two non-parallel sides. To find the area, you take the average of the two base lengths, multiply by the height, and divide by 2. The formula is:

Area = ½ × (Base₁ + Base₂) × Height

This formula works for all types of trapezoids, whether they're right-angled or slanted. Knowing how to calculate this is useful for geometry class, home projects, or even design work.
