# Python Program to Calculate the Area of a Triangle

Python Program to Calculate the Area of a Triangle

If a, b and c are three sides of a triangle. Then,

s = (a+b+c)/2

area = √(s(s-a)*(s-b)*(s-c))

Source Code

# 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)

Run Code

Output

The area of the triangle is 14.70
