Answer 2

Calculating the Area and Perimeter of a Square

To find the area and perimeter of a square with a side length of 7 cm, we can use the following formulas and calculations.

Area of a Square: The area of a square is given by the formula: \( A = s^2 \), where \( s \) is the length of a side.

Using the given side length of 7 cm, we can calculate the area as follows: \[ A = 7^2 = 49 \, \text{cm}^2 \]

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

Using the given side length of 7 cm, we can calculate the perimeter as follows: \[ P = 4 \times 7 = 28 \, \text{cm} \]

Therefore, the area of the square is 49 square centimeters, and the perimeter is 28 centimeters.
