Area of a Square Lesson
Square Area Formula
The formula for area of a square is given as:
A = s2
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 = s2
- A = 102 = 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 = s2
- 81 = s2
- Now let's solve for the side length s
- 81 = s2
s = 9 - The side length is 9 meters.
