Python program to find area of triangle

The program to find area of triangle in python is as follows :

 

# Owner : TutorialsInhand Author : Devjeet Roy
 
s1 = float(input('Enter first side: '))  
s2 = float(input('Enter second side: '))  
s3 = float(input('Enter third side: '))  
   
s = (s1 + s2 + s3) / 2  
   
area = (s*(s-s1)*(s-s2)*(s-s3)) ** 0.5  
print("The area of the triangle is:", round(area,2))

The output of the python program to find area of triangle is as follows :

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter first side: 30
Enter second side: 40
Enter third side: 20
The area of the triangle is: 290.47

Few important tips about this program:

1. The input data type provided by the input() function is of string data type, we convert that to float data type for mathematical computation.

2. Here, we have used the formula for finding the area of a scalene triangle.

3. We have used the round() function here, to round off the float output upto 2 decimal places.
