The perimeter that a rhombus is the sum of every its sides. Rhombus is a quadrilateral in which all 4 sides are of the same measure. A rhombus is always a parallelogram but a parallelogram might not have to be a rhombus always. Let united state study much more about the perimeter of rhombus in this article.

The perimeter of a rhombus is the full measure that its boundary and it is calculated by including the length of every its sides. Since all the four sides that a rhombus room equal, the basic formula to find the perimeter that a rhombus is: Perimeter = 4a; wherein 'a' is the side of the rhombus. The perimeter of a rhombus is express in straight units favor inches, yards, centimeters, and so on.

Properties of a Rhombus

There space some straightforward properties that help us to identify a rhombus. Watch the complying with rhombus ABCD to relate come its properties given below.


We have the right to identify and distinguish a rhombus with the help of the adhering to properties:

All four sides are equal.The the contrary sides space parallel.The the opposite angles room equal.The sum of any kind of two surrounding angles is 180o.The diagonals bisect each various other at ideal angles.Each diagonal line bisects the vertex angles.

Now, let us read around the formulas the are supplied to find the perimeter the a rhombus in different cases. The formulas different according come the known dimensions.

Perimeter that Rhombus Formula through Sides

As disputed earlier, the perimeter of a rhombus is the sum of the lengths of every its sides. We recognize that the political parties of a rhombus room of equal lengths. Permit us think about a rhombus that side size 'a'. Then, the perimeter of the rhombus is a + a + a + a i m sorry is 4a. Thus, the perimeter the the rhombus formula is: ns = 4a.


Example: Find the perimeter the a rhombus that has actually a side length of 10 units.


The side size of the given rhombus, a = 10 units.

Its perimeter = 4a = 4 × 10 = 40 units.

Perimeter the Rhombus Formula v Diagonals

When the size of the diagonals that a rhombus is known, we find the side size of the rhombus utilizing the Pythagoras theorem. Here, we exploit the complying with properties the a rhombus:

Let us consider a rhombus ABCD v diagonals p and also q and with side size 'a'.


Let us take triangle AOD. Since the diagonals bisect at right angles, AO have the right to be created as p/2 and also OD can be created as q/2. Now, if we apply the Pythagoras theorem for triangle AOD, we get

(a^2 = dfracp^24+dfracq^24)

(a =dfrac sqrtp^2+q^22)

Since we recognize that Perimeter that the rhombus = 4a

Let us substitute the value of : (a =dfrac sqrtp^2+q^22) in the formula: p = 4a

Perimeter that rhombus = 4 × (dfrac sqrtp^2+q^22) (or)

Perimeter of rhombus = (2sqrtp^2+q^2)

Note: We do not have to remember this formula. We have the right to use the Pythagoras organize to uncover the side size of the rhombus making use of the diagonals and also then we can use the perimeter that rhombus formula to be, p = 4 × next length.

Example 1: Find the perimeter that a rhombus with diagonals 8 inches and also 6 inch respectively.


Method 1:

The lengths the the diagonals that the given rhombus are, ns = 8 inches and also q = 6 inches.

Using the perimeter the rhombus formula utilizing diagonals,

Perimeter = 2 (sqrtp^2+q^2)

Perimeter = 2 (sqrt8^2+6^2) = 2 (sqrt100) = 2 × 10 = 20 inches.

Method 2:

Let us assume that the side length of the rhombus is 'a'.

Since the diagonals bisect each other at best angles,


By Pythagoras theorem,

a2 = 32 + 42 = 25

a = 5 inches.

Thus, the perimeter of the rhombus is, 4a = 4 × 5 = 20 inches.

Answer: The perimeter the the provided rhombus = 20 inches.
