A rhombus is a quadrilateral in which length of all the sides is equal. It is also known as equilateral quadrilateral since equilateral means that all the sides are of equal length. A rhombus looks like a diamond.

## Properties of Rhombus

- All sides are of equal length.
- Opposite sides are parallel.
- Opposite angles are equal.
- Diagonals bisect each other at 90⁰.

## Area of Rhombus

Area of rhombus can be calculated by 3 different formulae:

- When the height and length of the side is given.

*A= H x a*

- When the length of side and angle of side is given.

*A= a**² sin(A)*

- When the length if the diagonals is given.

**A= (p x q)/2**

## ParameterofRhombus

The formula to find the area of rhombus is same as square because in rhombus also length of all sides is equal.

*P= 4a*
