Heron’s formula is a common way to calculate the area of a triangle. In this Python tutorial, you will learn how to write a simple Python program to calculate the area of a triangle.

**Prerequisites to Create The Python Program to Calculate the Area of a Triangle**

**Algorithm to Find the Area of a Triangle Using Python **

**1st Step**– Ask the user to enter the length of the three sides of the triangle.**2nd Step**– Next, calculate the area using Heron’s formula.**3rd Step**– At last, use the print function and display the area of the triangle on the screen.

**Heron’s Formula**

Area of a triangle= √(s(s-a)*(s-b)*(s-c))

Here, s = (a+b+c)/2, and a, b, and c are the length of the three sides of the given triangle.

**Python Program to Calculate the Area of a Triangle**

import math a= float(input("Enter the length of first side: ")) b= float(input("Enter the length of second side: ")) c= float(input("Enter the length of third side: ")) s= (a+b+c)/2 area = math.sqrt((s*(s-a)*(s-b)*(s-c))) print("The area of Triangle is: {0:.2f}".format(area))

**Input**

Enter the length of first side: 4 Enter the length of second side: 13 Enter the length of third side: 15

**Output**

The area of Triangle is: 24.00

### Conclusion

In this example, we have used Heron’s formula to calculate the area of the triangle. It is a straightforward program with only a few lines of code. Moreover, to enhance your Python logic-building skill, you can use some other logic to find the area of the triangle.
