# Rhombus Formula

A rhombus is a type of Parallelogram only. Its diagonals perpendicularly bisect each other.

## Formula of Area of Rhombus / Perimeter of Rhombus

There are 3 ways to find the area of Rhombus. Find the formulas for same and Perimeter of Rhombus in the table below.

 Perimeter = 4a Where a is the side. Area = ah where a is the length of the side h is the altitude (height). Area =d1d2 / 2 where d1 is the length of a diagonal d2 is the length of the other diagonal Area = a2 sinx where a is the length of any side x is an interior angle sin is the sine function

## Area of Rhombus Questions

Question: Find the area of a rhombus whose length of the diagonals is 10 cm and 14 cm respectively.

Solution: Given,
d1 = 1 cm
d2 = 14 cm
Area = (d1d2)/2
= (10 ×14)/2
= 70 cm2
