# Area of Trapezoid

To calculate the **area of a trapezoid** we need to know the length of both of its opposite sides and its perpendicular heigth. The **area of the trapezoid** means a largeness of a plane which the trapezoid occupies. For example an area of a trapezoidal garden. The elementary unit of the area is one square metre, it means the second power of one metre (1 m^{2}).

## Area of Trapezoid - formula

**Area of Trapezoid** = 1/2 × (base length a + base length c) × perpendicular height

A = 1/2 × (a + c) × h
