# Perimeter of a Rhombus

## The Perimeter Formula

A rhombus is a quadrilateral with 4 equal sides, a pair of opposing equal acute angles, and a pair of opposing equal obtuse angles.

The formula for perimeter of a rhombus is given as:**P = 4s**

Where *P* is the perimeter and *s* is the side length.

### Example Problems

Problem 1:

Find the perimeter of a rhombus with a side length of 10.

Solution:

Since we are given the side length, we can plug it straight into the formula.

P = 4s

P = 4(10) = 40**The perimeter of the rhombus is 40.**

Problem 2:

A rhombus shaped table is measured to have a perimeter of 192 cm. What is the length of one of the table’s sides?

Solution:

Let’s plug the perimeter into the equation and solve for side length.

P = 4s

192 = 4s, s = 192/4

s = 48 cm.**The table’s side length is 48 cm.**
