Write a Python program to find the area of a triangle
# Three sides of the triangle is a, b and c:
side1 = float(input('Enter first side: '))
side2 = float(input('Enter second side: '))
side3 = float(input('Enter third side: '))
# calculate the semi-perimeter
s = (side1 + side2 + side3) / 2
# calculate the area
Area_by_T4Tutorials = (s*(s-side1)*(s-side2)*(s-side3)) ** 0.5
print('The area of the triangle is %0.2f' %Area_by_T4Tutorials)
Output
Enter first side: 6
Enter second side: 7
Enter third side: 4
The area of the triangle is 11.98
