# Perimeter of a Square

## The Perimeter Formula

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

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

### Example Problems

**Problem 1:**

A square has a side length of 5. What is the perimeter?

Solution:

P = 4s

P = 4(5) = 20**The perimeter of the square is 20.**

**Problem 2:**

A square has an area of 36. What is the perimeter?

Solution:

The area formula is A = s^{2}, we can find side length by solving for s.

36 = s^{2}

√36 = s

s = 6

We have found the side length is 6. Plugging this into the perimeter formula we get:

P = 4s

P = 4(6) = 24**The perimeter of the square is 24.**

**Problem 3:**

A square table is measured to have a perimeter of 2 meters. What is the length of one of its sides?

Solution:

Let’s plug the perimeter into the formula and solve for s.

P = 4s

2 = 4s

2/4 = s

s = 0.5**The side length of the table is 0.5 meters.**
