Enter Trapezoid Dimensions

Provide the lengths of the two parallel bases (a and b) and the height (h) of the trapezoid to calculate its area.

Base a:

units

Length of the top base of the trapezoid.

Base b:

units

Length of the bottom base of the trapezoid.

Height h:

units

Perpendicular height between the bases.

Area of Trapezoid:

Formula

The formula for the area of a trapezoid is given by:

$$Area = \frac{1}{2} \times (base_1 + base_2) \times height$$

Where base₁ and base₂ are the lengths of the parallel sides, and height is the perpendicular distance between them.

Understanding Trapezoids

A trapezoid (or trapezium) is a quadrilateral with at least one pair of parallel sides, called bases. The other two sides are non-parallel. The area of a trapezoid is found by averaging the lengths of the two bases and multiplying by the height.

Formula Explained:

Bases (a and b): These are the parallel sides of the trapezoid.
Height (h): This is the perpendicular distance between the bases.
Area = 1/2 × (a + b) × h: This formula efficiently calculates the space enclosed within the trapezoid.

This calculator simplifies the process of finding the area, making it easy for students, educators, and anyone needing quick geometry calculations.
