Python Program to Calculate the Area of a Triangle

Write a Python program to accept 3 sides of triangle and find the area of triangle.

s = (a+b+c)/2

area = √(s(s-a)*(s-b)*(s-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)

Enter first side: 4

Enter second side: 5

Enter third side: 6

The area of the triangle is 9.92
