**AREA OF A TRIANGLE IN PYTHON**

In geometry, Heron’s formula, named after Hero of Alexandria, gives the area of a triangle by requiring no arbitrary choice of side as base or vertex as origin.

Heron’s formula states that the area of a triangle whose sides have lengths a, b, and c is where s is the semi-perimeter of the triangle; that is,

**Program**

# Python Program to find the area of triangle

#Take inputs from the user

a = float(input(‘Enter the first side: ‘))

b = float(input(‘Enter the second side: ‘))

c = float(input(‘Enter the 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)

input(“Press Enter to Exit”)

**Output**
