Trapezoid Area Calculator
Calculate the area of a trapezoid from its two parallel bases and height. It is useful for study, lab preparation, engineering notes, or checking a calculation where consistent units matter.
How to use this calculator
Formula
Area = 1/2 × (base₁ + base₂) × height.
Quick check
Check the result against a rough estimate. A quick mental check can reveal a misplaced decimal or an incorrect unit. For technical or academic work, write down the units alongside the numbers. A mathematically correct calculation can still be misleading if the units are wrong.
