Answer 2

Task Solution: Finding the Area of a Square with a Perimeter of 12 cm

To find the area of a square with a perimeter of 12 cm, we can use the formula for the perimeter of a square and then calculate the area using the side length.

Step 1: Calculate the Side Length of the Square The formula for the perimeter of a square is P = 4a, where P is the perimeter and a is the side length of the square. We can rearrange this formula to solve for a: a = P / 4

Using the given perimeter P = 12 cm: a = 12 / 4 a = 3 cm

Step 2: Calculate the Area of the Square The formula for the area of a square is A = a^2, where A is the area and a is the side length of the square. Substituting the calculated side length: A = 3^2 A = 9 cm^2

Therefore, the area of the square with a perimeter of 12 cm is 9 square centimeters.

Conclusion

The area of the square is 9 square centimeters.
