In this python article, we would love to share with you algorithm to write a program to accept the length and breadth of a rectangle and print its area in python.

Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

The formula of the Area of Rectangle

When you know the width and height. So you can calculate the area of a rectangle using below formula:

Area = Width * Height

Perimeter is the distance around the edges. You can calculate perimeter of a rectangle using below formula:

Perimeter = 2 * (Width + Height)

Write a Program to find the Area of a Rectangle and Perimeter of a Rectangle in Python

Follow the below steps and Write a Program to find the Area of a Rectangle and Perimeter of a Rectangle in Python:

Allow the User to input the Width and Height of a rectangle.
Next, we are calculating the area as per the formula Area = width * height.
In the next line, We are calculating the Perimeter of a rectangle Perimeter = 2 * (width + height).
Print the Perimeter and Area of a rectangle.

# Write a Program to find the Area of a Rectangle and 
# Perimeter of a Rectangle in Python

w = float(input('Please Enter the Width of a Rectangle: '))
h = float(input('Please Enter the Height of a Rectangle: '))

# calculate the area
Area = w * h

# calculate the Perimeter
Perimeter = 2 * (w + h)

print("\n Area of a Rectangle is: %.2f" %Area)
print(" Perimeter of Rectangle is: %.2f" %Perimeter)

After executing the python program, the output will be:

Please Enter the Width of a Rectangle:  10
Please Enter the Height of a Rectangle:  5

Area of a Rectangle is: 50.00
Perimeter of Rectangle is: 30.00

Python Program to Calculate the Area of a Rectangle using Function

Follow the below steps and Python Program to Calculate the Area of a Rectangle using Function:

Defined the function with two arguments using def keyword.
Calculating the perimeter and Area of a rectangle inside functions.
Allow the User to input the Width and Height of a rectangle.
Print the Perimeter and Area of a rectangle.

# Write a Program to find the Area of a Rectangle and 
# Perimeter of a Rectangle in Python using functions

def AreaOfRectangle(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)
    
width = float(input('Please Enter the Width of a Rectangle: '))
height = float(input('Please Enter the Height of a Rectangle: '))

AreaOfRectangle(width, height)

After executing the python program, the output will be:

Please Enter the Width of a Rectangle:  15
Please Enter the Height of a Rectangle:  5

 Area of a Rectangle is: 75.00
 Perimeter of Rectangle is: 40.00
