Python Program to Calculate the Area of a Triangle

To understand this example, you should have the knowledge of the following Python programming topics:

If a, b and c are three sides of a triangle. Then,

s = (a+b+c)/2
area = √(s(s-a)*(s-b)*(s-c))

Source Code

Output

The area of the triangle is 14.70

In this program, area of the triangle is calculated when three sides are given using Heron's formula.

If you need to calculate area of a triangle depending upon the input from the user, input() function can be used.
