Calculating the Area and Perimeter of a Square

To find the area and perimeter of a square with a side length of 3 cm, we can use the following formulas:

Area of a Square: The area (S) of a square is given by the formula S = side length * side length.

Perimeter of a Square: The perimeter (P) of a square is given by the formula P = 4 * side length.

Let's calculate the area and perimeter using the given side length of 3 cm.

Calculating the Area

The area (S) of a square with a side length of 3 cm is calculated as follows: S = side length * side length S = 3 cm * 3 cm S = 9 cm^2

Therefore, the area of the square is 9 square centimeters.

Calculating the Perimeter

The perimeter (P) of a square with a side length of 3 cm is calculated as follows: P = 4 * side length P = 4 * 3 cm P = 12 cm

Therefore, the perimeter of the square is 12 centimeters.

So, for a square with a side length of 3 cm: - The area is 9 square centimeters. - The perimeter is 12 centimeters.
