Answer for screen readers
9 in²
Steps to Solve
- Recall the formula for the area of a square
The area of a square is calculated by multiplying the length of one side by itself. If $s$ is the side length, the area $A$ is $A = s \times s = s^2$.
- Substitute the given side length into the formula
We are given that the square measures 3 inches by 3 inches, meaning each side is 3 inches long. So, $s = 3$ inches. We can calculate the area: $A = 3 \times 3$.
- Calculate the area
$A = 3 \times 3 = 9$ square inches.
9 in²
More Information
The area of the square is 9 square inches, or 9 $in^2$.
Tips
A common mistake is to add the sides instead of multiplying them, which would give the perimeter instead of the area. Another mistake is to multiply the side length by 4.
