Hey guys, in this blog we will see a **Python Program to Calculate the Area of a Triangle** using 2 different formulas.

Table of Contents

## Example 1: Using the Base and Height of the Triangle

# Python Program to Calculate the Area of a Triangle # base and height of triangle base = 12 height = 12 #calculating area of the triangle area_of_triangle = 0.5*base*height print(f'The area of a rectangle with base {base} and height {height} = {area_of_triangle}')

**Output**

The area of a rectangle with base 12 and height 12 = 72.0

Here we have used the simple formula for calculating the area of a triangle which is:

**Area of Triangle = 0.5*base*height.**

## Example 2: Using 3 sides of a Triangle

# Python Program to Calculate the Area of a Triangle # base and height of triangle side1 = 4 side2 = 13 side3 = 15 #calculating area of the triangle s = (side1+side2+side3)/2 area_of_triangle = (s*(s-side1)*(s-side2)*(s-side3))**0.5 print(f'The area of a rectangle with sides {side1}, {side2} and {side3} = {area_of_triangle}')

**Output**

The area of a rectangle with sides 4, 13 and 15 = 24.0

Here we have used Heron’s formula to calculate the area of the triangle. The formula for it is given below:

**Area of Triangle = (s(s-side1)(s-side2)(s-side3))*0.5**
