Calculate the Area of a Triangle
Course- Python >
Source Code
# Python Program to find the area of triangle
# Three sides of the triangle a, b and c are provided by the user
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)
Output
Enter first side: 5 Enter second side: 6 Enter third side: 7 The area of the triangle is 14.70
In this program, we asked users to enter the length of three sides of a triangle. We used the Heron's Formula to calculate the semi-perimeter and hence the area of the triangle.
