Mathematical formula:

Here is the semi-perimeter and a, b and c are three sides of the triangle. Let's understand the following example.

Program:

# Three sides of the triangle is a, b and c:  
a = float(input('Enter first side: '))  
b = float(input('Enter second side: '))  
c = float(input('Enter third side: '))  
  
# calculate the semi-perimeter  
s = (a + b + c) / 2  
  
# calculate the area  
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5  
print('The area of the triangle is %0.2f' %area)   

Output:

Enter first side: 5
Enter second side: 6
Enter third side: 7
The area of the triangle is 14.70
