Python program to find the area of a triangle
Mathematical formula:
Area of a triangle = (s*(s-a)*(s-b)*(s-c))-1/2
Here s is the semi-perimeter and a, b and c are three sides of the triangle.
See this example:
- # 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:
Note: %0.2f floating point specifies at least 0 wide and 2 numbers after decimal. If you use %0.5f then it will give 5 numbers after decimal.
