Rhombus is a quadrilateral with all sides equal.
A rhombus is a special case of a parallelogram. Therefore, all properties of a parallelogram apply to a rhombus. A rhombus with all angles equal is called a square.
Perimeter of a Rhombus
$$C=4 \times a$$
where,
a— side length of the rhombus.
Area of a Rhombus
Area of a rhombus through side length and height:
$$S=a \times h,$$
where,
a— side length of the rhombus.
h— height of the rhombus.
Area of a rhombus through diagonals:
$$S=\frac{d_{1} \times d_{1}}{2},$$
where d1, d2 are the diagonals of the rhombus.
Area of a rhombus through side length and angle:
$$S=a^{2} \times \textrm{sin}(\alpha),$$
where,
a— side length of the rhombus.
α— angle of the rhombus.
