Double Value - Python Programming Exercise

This Python program calculates the perimeter, area, and diagonal of a rectangle, based on the given width and height. The perimeter is calculated by adding up all four sides of the rectangle, the area is determined by multiplying the width and height, and the diagonal is found using the square root formula, where the diagonal is the hypotenuse of a right-angled triangle formed by the width and height. The math.sqrt(x) function is used to calculate the square root of the sum of the squares of the width and height, which gives the length of the diagonal. This exercise demonstrates the use of basic geometry formulas in Python, incorporating essential math functions and user input. By calculating the perimeter, area, and diagonal, this program helps in understanding how to manipulate and compute values in Python.

Double Value

 Objective

Develop a Python program that calculates the perimeter, area, and diagonal of a rectangle, given its width and height.

(Hint: use y = math.sqrt(x) to calculate a square root)

 Example Python Exercise

 Copy Python Code 
import math  # Import the math module to use sqrt function

# Prompt the user for the width and height of the rectangle
width = float(input("Enter the width of the rectangle: "))
height = float(input("Enter the height of the rectangle: "))

# Calculate the perimeter, area, and diagonal
perimeter = 2 * (width + height)
area = width * height
diagonal = math.sqrt(width**2 + height**2)  # Using Pythagoras' theorem to calculate diagonal

# Display the results
print(f"The perimeter of the rectangle is: {perimeter}")
print(f"The area of the rectangle is: {area}")
print(f"The diagonal of the rectangle is: {diagonal}")

 Output

Case 1:
Enter the width of the rectangle: 5
Enter the height of the rectangle: 12
The perimeter of the rectangle is: 34.0
The area of the rectangle is: 60.0
The diagonal of the rectangle is: 13.0

Case 2:
Enter the width of the rectangle: 8
Enter the height of the rectangle: 15
The perimeter of the rectangle is: 46.0
The area of the rectangle is: 120.0
The diagonal of the rectangle is: 17.4642491965977
