# Python code to calculate area of a triangle
# Read input values
a = float(input('Enter Value 1: '))
b = float(input('Enter value 2: '))
c = float(input('Enter value 3: '))
# calculate the semi-perimeter
s = (a + b + c) / 2
# calculate the area of trainagle
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('The area of the triangle is %0.2f' %area)
OUTPUT:
Enter Value 1: 10 Enter value 2: 11 Enter value 3: 12 The area of the triangle is 51.52
