# Area of a Square

## Square Area Formula

The formula for area of a square is given as:**A = s ^{2}**

Where

*A*is the area and

*s*is the side length.

### Example Problems

**Problem 1:**

Find the area of a square with a side length of 10.

Solution:

1.) Plugging the side length into the formula, we get:

A = s^{2}

A = 10^{2} = 100

2.) **The area of the square is 100.**

**Problem 2:**

A square’s area is measured to be 81 square meters. What is its side length in meters?

Solution:

1.) Let’s plug the area into the formula first.

A = s^{2}

81 = s^{2}

2.) Now let’s solve for the side length *s*.

81 = s^{2}

s = 9

3.) **The side length is 9 meters.**

# Area Of A Square

In this lesson, we go over how to find the area of a square. At the end there will be a practice problem to text your knowledge on the subject.

## Area of a square formula

Area = side^2 = side * side

#### HOW TO FIND THE AREA OF A SQUARE

To find the area of a square, take a side length and multiply it by itself (also known as squaring a number)

Ex. 5^2 = 5 * 5 = 25
