Find Perimeter of a Square

Theory:

The perimeter of a square is calculated by adding the lengths of all its sides. Since all sides of a square are equal, the perimeter is given by 4 * side, where side denotes the length of one of its sides.

Python Code:

def calculate_square_perimeter(side):
    return 4 * side

# Taking input for the side length of the square and calculating its perimeter
def calculate_and_display_square_perimeter():
    side = float(input("Enter the side length of the square: "))
    perimeter = calculate_square_perimeter(side)
    print("Perimeter of the square:", perimeter)

calculate_and_display_square_perimeter()

Example Output 1:

Enter the side length of the square: 5

Perimeter of the square: 20.0

Example Output 2:

Enter the side length of the square: 7.5

Perimeter of the square: 30.0

Code Explanation:

The function calculate_square_perimeter(side) calculates the perimeter of a square by multiplying the length of one of its sides by 4.

The function calculate_and_display_square_perimeter() takes input for the side length of the square, calculates its perimeter using the aforementioned function, and displays the result.
