# Python Program to Calculate the Area of a Triangle

In this post, we will see how to calculate area of triange and print it in Python.

## Problem

Calculate area of the triangle given three sides.

## Solution

You can calcualte area of the traingle using Haron’s formula.

Here is simple python program to calculate area of the tringle.

```
# Three sides of triangle
a=10
b=20
c=15
s=(a+b+c)/2
area=(s*(s-a)*(s-b)*(s-c))**0.5
print("Area of the triangle is: ",area)
```

**Output:**

Area of the triangle is: 72.61843774138907

That’s about calculating area of triange in python.
