## How to Calculate the Area of Triangle in Python?

Are you looking for a quick and easy way to determine the area of a triangle? If so, you’ll love this Python Program example. In this Python program, we are going to use the Heron’s Formula (mathematical formula) to find the area of a triangle. Type in the coordinates of the base, height of triangle , and point on the edge that you want to calculate the area of, and the program will do the rest. This program is perfect for students or anyone who wants an easy way to calculate area quickly and easily.

Area of Triangle is calculated as:

`Area of a Triangle = √(s*(s-a)*(s-b)*(s-c)) `

Where s is given by basic formula:

`s = (a + b + c )/ 2 `

a,b,c are the sides of triangle.

Let’s look at different examples of Python Program to Find the Area of a Triangle.

### Example No. 01

```
a = 10
b = 15
c = 18
s = (a + b + c) / 2
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('The Area of the Triangle is %0.2f' %area)
```

#### Output

### Example No. 02

```
x = float(input('Enter the length of First Side: '))
y = float(input('Enter the length of Second Side: '))
z = float(input('Enter the length of Third Side: '))
s = (x + y + z) / 2
Area = (s*(s-x)*(s-y)*(s-z)) ** 0.5
print('The Area of the Triangle is %0.2f' %Area)
```

## Python Program to Find the Area of a Triangle: Using Function

First we will import math module, and a function with three arguments will be defined. The area of a triangle will be found using math.sqrt() with Heron’s Formula. Here’s how it works:

```
import math
def AreaOfTriangle(a, b, c):
Perimeter = a + b + c
s = (a + b + c) / 2
Area = math.sqrt((s*(s-a)*(s-b)*(s-c)))
print(" The Area of a Triangle is %0.2f" %Area)
a = float(input('Enter the First side a : '))
b = float(input('Enter the Second side b : '))
c = float(input('Enter the Third side of c : '))
AreaOfTriangle(a, b, c)
```

#### Output

## FAQs

### What is the basic syntax of a python program that will calculate the area of a triangle?

The python triangle program that will calculate the area of a triangle can be written as follows:

triangle = (a, b, c)

area = triangle.Area()

The Area function takes in three arguments and returns the surface area of the given triangle.

### Have you ever written any programs in Python before? If so, how did you find it challenging/easy to build programs in this language?

Yes, I have written a few programs in Python; as someone familiar with Java and Python, writing programs in Python was very easy for me. The syntax is quite similar to java, so it’s not difficult to understand how a program works once you get started. Additionally, the rich standard library with Python makes developing software much easier than using less popular languages like Arduino or NodeJS.
