## Python Program to find area of Triangle

In this post “Python Program to find the area of Triangle, you’ll learn how to find the area of Triangle in Python

### Python Program to find area of Triangle

To properly understand this example to find the area of triangle in Python, you should have the knowledge of following Python programming topics:

1.Input, Output, and Import

2.Variables and Data Types

3.Operators

Area of a triangle is equal to half of the product of its base and height.

The height of a triangle is the perpendicular distance from a vertex to the base of the triangle.

(Note: 12 is the height, not the length of the left-hand side)

Height = h = 12

Base = b = 20

Area = ½ bh = ½ × 20 × 12 = 120

here if a, b, and c are three sides of the triangle so this can be solved by the mathematical formula

## Python Program to find the area of Triangle

a = 5 b = 6 c = 7 # Uncomment below to take inputs from 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**

The area of the triangle is 14.70

In this program, the area of the triangle is calculated when three sides are given using Heron’s formula.
