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 = 4 x ½ (ab)

where

b is the length of the base

a is the altitude (height).

Area =d1d2 / 2

where

d1 is the length of a diagonal

d2 is the length of the other diagonal

Area = Sin2×sinx

where

s 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
