# Area of Rhombus

To calculate the **area of a rhombus**, we need to know a length of its base side and perpendicular height. The rhombus is 2D shape, which has two pairs of parallel sides. All of its sides have the same length. The **area of the rhombus** means a size of a cover area by the rhombus. For example, the **area of a rhombus** garden. The elementary unit of the area is one square metre, it means the second power of one metre (1 m^{2}).

## Area of Rhombus - formula

**Area of Rhombus** = base length x perpendicular height

A = a × h
