This article shows that python program to find a area of triangle.
Mathematical formula to find the area of triangle:
Area of a triangle = (s*(s-x)*(s-y)*(s-z))1/2
Here s is the semi-perimeter and x, y and z are three sides of the triangle.
Semi-Perimeter of a triangle = (x + y + z) / 2
Python Program to do arithmetical calculation.
# Three sides of the triangle is x, y and z: x = float(input('Enter first side: ')) y = float(input('Enter second side: ')) z = float(input('Enter third side: ')) # calculate the semi-perimeter s = (x + y + z) / 2 # calculate the area area = (s*(s-x)*(s-y)*(s-z)) ** 0.5 print('The area of the triangle is %0.3f' %area)
1. Here ** is exponent operator for calculating exponent of any number. This operator works for all positive real numbers. But for negative or complex numbers, it not works.
2. %0.3f floating point specifies at least 0 wide and 3 numbers after decimal. If you use %0.4f then it will give 4 numbers after decimal.
See this example to clarify the second point of the Note:
