Program to Find Area of a Triangle in Python Using Base and Height

Calculating the area of a triangle is one of the basic programs often used in programming tutorials and beginner exercises. This Python program demonstrates how to calculate the area of a triangle using the standard mathematical formula involving base and height.

The formula used is:

Area = 0.5 × base × height

In this post, we will go through a step-by-step guide to writing a simple and beginner-friendly Python script to compute the area of a triangle.

Python Code to Find Area of a Triangle

# Program to calculate the area of a triangle

# Input values for base and height
base = float(input("Enter the base of the triangle: "))
height = float(input("Enter the height of the triangle: "))

# Calculate area
area = 0.5 * base * height

# Display the result
print(f"The area of the triangle is: {area}")

How the Program Works

1. The program first prompts the user to enter the base and height of the triangle.
2. It then uses the formula area = 0.5 * base * height to calculate the area.
3. The result is displayed using Python’s print() function with formatted output.
