Python Program to find Area of a Rectangle and Perimeter of a Rectangle

  • This program allows the user to enter width and height of the rectangle. Using those values we will calculate the Area of a rectangle and perimeter of a rectangle.

Sample Code

# Python Program to find Area of a Rectangle
 
width = float(input('Please Enter the Width of a Rectangle: '))
height = float(input('Please Enter the Height of a Rectangle: '))
 
# calculate the area
Area = width * height
 
# calculate the Perimeter
Perimeter = 2 * (width + height)
 
print("\n Area of a Rectangle is: %.2f" %Area)
print(" Perimeter of Rectangle is: %.2f" %Perimeter)

Python Program to find Area of a Rectangle using functions

  • This program allows the user to enter the width and height of a rectangle.
  • We will pass those values to the function arguments to calculate the area of a rectangle.

Sample Code

# Python Program to find Area of a Rectangle using Functions
 
def Area_of_a_Rectangle(width, height):
 
    # calculate the area
    Area = width * height
 
    # calculate the Perimeter
    Perimeter = 2 * (width + height)
 
    print("\n Area of a Rectangle is: %.2f" %Area)
    print(" Perimeter of Rectangle is: %.2f" %Perimeter)
 
Area_of_a_Rectangle(6, 4)
