Python: Calculate Rectangle Perimeter

1. Introduction

A rectangle is one of the most fundamental shapes in geometry. It is characterized by its length and breadth (or width). Often in practical scenarios, such as in architecture or in basic mathematical problems, it is necessary to determine the perimeter of a rectangle. In this article, we'll develop a Python program that calculates the perimeter of a rectangle.

2. Program Overview

The program will:

1. Ask the user to input the length and breadth (width) of the rectangle.

2. Calculate the perimeter of the rectangle.

3. Display the calculated perimeter.

3. Code Program

# Taking the dimensions of the rectangle as input
length = float(input("Enter the length of the rectangle: "))
breadth = float(input("Enter the breadth (width) of the rectangle: "))

# Calculating the perimeter
perimeter = 2 * (length + breadth)

# Displaying the perimeter
print(f"The perimeter of the rectangle with length {length} and breadth {breadth} is: {perimeter}")

Output:

Enter the length of the rectangle: 5
Enter the breadth (width) of the rectangle: 3
The perimeter of the rectangle with length 5.0 and breadth 3.0 is: 16.0

4. Step By Step Explanation

1. The program starts by collecting the dimensions of the rectangle from the user. The input function is utilized to obtain this data, which returns values in string format. To perform the necessary arithmetic, these string values are converted into floating-point numbers using the float function.

2. Following this, the formula for the rectangle's perimeter is applied. By multiplying the sum of the length and breadth by 2, we obtain the desired result.

3. Ultimately, the print function is utilized to output the original dimensions alongside the calculated perimeter.

By using Python, this program aptly demonstrates how simple mathematical problems can be swiftly and accurately resolved.
