## Area of a Square Lesson

### 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.

INTRODUCING

### Area of a Square Example Problems

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

#### Example Problem 1

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

Solution:

- Plugging the side length into the formula, we get:
- A = s
^{2} - A = 10
^{2}= 100 **The area of the square is 100.**

#### Example Problem 2

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

Solution:

- Let's plug the area into the formula first.
- A = s
^{2} - 81 = s
^{2} - Now let's solve for the side length
*s* - 81 = s
^{2}

s = 9 **The side length is 9 meters.**
