Use this trapezoid area calculator to quickly calculate trapezoid area using the lengths of the two bases and height. Apply the area of trapezoid formula for accurate results.
a = base a
b = base b
h = height
Add the bases, divide by 2, then multiply by height.
| Base a | Base b | Height | Area |
|---|---|---|---|
| 5 | 7 | 4 | 24 |
| 8 | 10 | 6 | 54 |
| 12 | 8 | 5 | 50 |
| 15 | 10 | 7 | 87.5 |
| 20 | 15 | 10 | 175 |
1. Measure both base lengths.
2. Measure the height.
3. Add the bases, divide by 2, multiply by height.
This trapezoid area calculator automatically computes the area using the correct area of trapezoid formula with up to six decimal places.
• Trapezoids have one pair of parallel sides.
• The height is perpendicular to the bases.
• The area formula works for any trapezoid regardless of angles.
• Trapezoids appear in architecture and design.
• The average of bases times height gives area efficiently.
