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:

1. Plugging the side length into the formula, we get:
2. A = s2
3. A = 102 = 100
4. 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:

1. Let's plug the area into the formula first.
2. A = s2
3. 81 = s2
4. Now let's solve for the side length s
5. 81 = s2
s = 9
6. The side length is 9 meters.
