Write a program to calculate the area of a triangle using python

To calculate the area of a triangle using Python, you can use the following steps:

1. Define the three sides of the triangle as `a`, `b`, and `c`.
2. Calculate the semiperimeter of the triangle as `s = (a + b + c) / 2`.
3. Calculate the area of the triangle as `A = sqrt(s * (s – a) * (s – b) * (s – c))`.

Here is an example of a Python program that calculates the area of a triangle:

​
import math
​
a = int(input(“Enter the length of side a: “))
b = int(input(“Enter the length of side b: “))
c = int(input(“Enter the length of side c: “))
​
s = (a + b + c) / 2
​
A = math.sqrt(s * (s – a) * (s – b) * (s – c))
​
print(“The area of the triangle is”, A)
​

This program will prompt the user to enter the lengths of the three sides of the triangle. It will then calculate the semi perimeter of the triangle and the area of the triangle. The area of the triangle will be printed on the console.
