Find Perimeter of a Parallelogram

Theory:

The perimeter of a parallelogram is calculated by adding the lengths of all its sides. Since opposite sides of a parallelogram are equal in length, its perimeter is given by 2 times the sum of the length of one pair of opposite sides.

Python Code:

def calculate_parallelogram_perimeter(side_length):
    return 2 * (side_length + side_length)

# Taking input for the length of one side of the parallelogram and calculating its perimeter
def calculate_and_display_parallelogram_perimeter():
    side_length = float(input("Enter the length of one side of the parallelogram: "))
    perimeter = calculate_parallelogram_perimeter(side_length)
    print("Perimeter of the parallelogram:", perimeter)

calculate_and_display_parallelogram_perimeter()

Example Output 1:

Enter the length of one side of the parallelogram: 5

Perimeter of the parallelogram: 20.0

Example Output 2:

Enter the length of one side of the parallelogram: 7.5

Perimeter of the parallelogram: 30.0

Code Explanation:

The function calculate_parallelogram_perimeter(side_length) calculates the perimeter of a parallelogram by summing the lengths of two sides and then doubling it.

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