## Perimeter of a Rhombus Lesson

### 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.

INTRODUCING

### Perimeter of a Rhombus Example Problems

Let's go through a couple of example problems together to practice finding the perimeter of a rhombus.

#### Example 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.**

#### Example 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.**
