314 In this program, you’ll learn how to find the area of a Triangle in Python

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

1. Input, Output, and Import
2. Variables and Data Type
3. Operators

The 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)

Base = b = 20

Area = ½ bh = ½ × 20 × 12 = 120

``````#for semi perimeter
s = (a+b+c)/2

# for area
area = √(s(s-a)*(s-b)*(s-c))``````

#### Program to find the Area of a 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``

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