# Area of a Rhombus Calculator with Side and Diagonal

A rhombus is a special type of quadrilateral parallelogram, where the opposite sides are parallel and opposite angles are equal and the diagonals bisect each other at right angles. There are many ways to calculate its area such as using diagonals, using base and height, using trigonometry, using side and diagonal. This online Area of a Rhombus Calculator with Side and Diagonal to find the rhombus area. The diagonals in rhombus are always perpendicular to each other.

#### Formula:

Area of a Rhombus = 1/2 x p x √(4 a^{2} - p^{2})
**Where,**
a = Side
p = Diagonal1

#### Example

**A rhombus has a side length of 7mm and diagonal of 12mm. What is its area?**

Area of a Rhombus = 1/2 x 12 x √((4 x 7^{2}) - 12^{2})

= 6 x √52

= 43.2666 mm^{2}.
