Python – Area of a Triangle

 

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”)
