Introdução

Trapezoid Calculator — Calculate the area of a trapezoid. Enter Base a, Base b, Height to get an instant, accurate result.

Fórmula

Area = ((a+b)/2) × h, where a and b are the two parallel sides and h is the perpendicular height between them.

Passo a passo

1. Enter the Base a.
2. Enter the Base b.
3. Enter the Height.
4. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Base a = 4, Base b = 6, Height = 3, the Trapezoid Calculator gives Area: 15.

Perguntas Frequentes

Why average the two parallel sides?

A trapezoid's area is equivalent to a rectangle with a width equal to the average of its two parallel sides.

Does the height need to be perpendicular?

Yes, h must be the perpendicular distance between the two parallel sides, not the length of a slanted side.

What inputs does the Trapezoid Calculator need?

You'll need to provide: Base a, Base b, Height. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Trapezoid Calculator?

The Trapezoid Calculator applies the formula exactly as calculated — Area = ((a+b)/2) × h, where a and b are the two parallel sides and h is the perpendicular height between them. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Trapezoid Calculator free to use?

Yes, the Trapezoid Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora de Trapézio

The Trapezoid Calculator uses a real, verifiable formula — Area = ((a+b)/2) × h, where a and b are the two parallel sides and h is the perpendicular height between them. — so results are accurate every time, not an approximation.
