Python: Calculate Triangle Area

1. Introduction

A triangle is a three-sided polygon that is one of the basic shapes in geometry. The area of a triangle can be calculated using different methods depending on the available information.

In this blog post, we will create a Python program to compute the area of a triangle given its base and height.

2. Program Overview

The program will:

1. Take the base and height of the triangle as input from the user.

2. Compute the area using the formula.

3. Display the area to the user.

3. Code Program

# Taking base and height as input
base = float(input("Enter the base of the triangle: "))
height = float(input("Enter the height of the triangle: "))

# Calculating area of the triangle
area = 0.5 * base * height

# Displaying the area
print(f"The area of the triangle with base {base} and height {height} is: {area}")

Output:

Enter the base of the triangle: 10
Enter the height of the triangle: 5
The area of the triangle with base 10.0 and height 5.0 is: 25.0

4. Step By Step Explanation

1. The program starts by taking the base and height of the triangle as input from the user. The input function returns a string, so we use the float function to convert it into a floating-point number.

2. Next, we calculate the area of the triangle using the formula mentioned earlier. The multiplication of the base and height is then divided by 2 (or multiplied by 0.5) to get the area.

3. Finally, the area is displayed using the print function.

This simple Python program demonstrates how we can use basic arithmetic operations and user input to solve geometric problems.
