About Area of Trapezoid

The Area of Trapezoid Calculator is a powerful and easy-to-use tool that allows you to calculate the area of any trapezoid in just seconds. Whether you’re solving math problems, planning architectural designs, or estimating material requirements, this calculator provides fast and accurate results based on the trapezoid's dimensions.

What Is a Trapezoid?

A trapezoid (also known as a trapezium in some regions) is a quadrilateral with at least one pair of parallel sides. These parallel sides are called the bases, and the perpendicular distance between them is the height.

Formula for Area of a Trapezoid:

The standard formula to calculate the area of a trapezoid is:

Area = (1/2) × (Base₁ + Base₂) × Height

Where Base₁ and Base₂ are the lengths of the parallel sides, and Height is the perpendicular distance between them.

Example Calculation:

If Base₁ = 10 cm, Base₂ = 6 cm, and Height = 5 cm, then:

Area = (1/2) × (10 + 6) × 5 = (1/2) × 16 × 5 = 40 cm²

✅ So, the area of the trapezoid is 40 square centimeters.
