Triangle Area

---

The problem

Take three sides of a triangle. And then calculate the area of the triangle.

How it works

To calculate the area of the triangle. First, calculate the half of the perimeter. Here perimeter is the sum of each side of the triangle.

Let’s call it s.

Then you have to perform square root of the formula like below-

s = (a+b+c)/2
area = √(s(s-a)*(s-b)*(s-c))

the code

import math

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 = math.sqrt(s*(s-a)*(s-b)*(s-c))
print('Area of your triangle is ', area)

Explanation

To calculate the square root. We used the math module. And call math.sqrt.

import math
print ( math.sqrt(4) )

This will give you 2 as output.

Similarly, math.sqrt(25) will give 5 as output.

This is something new you have learned this time.
