AreaOfTriangle.py

# Python Program to find the area of triangle when all three side-lengths are known!

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: " + area)
