Question : How to write a program to find the area of a triangle in Python

Solution : You can find the area of a given triangle in Python language. The formula to find the area of a triangle is :

Area of a triangle = (s*(s-a)*(s-b)*(s-c))-1/2

“s” is the semi-perimeter and “a, b and c” are three sides of the triangle.

# Three sides of the triangle is a, b and 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)

Output: Enter first side: 6 Enter second side: 12 Enter third side: 10 The area of the triangle is 29.93
