## 1. A Brief about Triangle and it’s Formulas

The

areaof atrianglecan be defined as the total space occupied by the three sides of any specifictrianglein a 2-dimensional plane.

The area of a** right-angled triangle **is simply equal to **half of the base multiplied by height**, which is simply **Area(A) = 1/2 *( b *h ).** Therefore, in order to calculate the area of a right-angled triangle, we need to know the *base (b)* and *height (h)* of it.

However, there is one more method or formula which can be used to calculate the area of any triangle. The method is using **Heron’s Formula**. Heron’s formula is generally used to calculate the area of any triangle.

Hence, we will discuss both the ways to calculate the area using python. Let’s implement each of them.

Some of the topics which will be helpful for understanding the program implementation better are:

## 2. Calculating the Area of Traingle using Heron’s Formula

For calculating the area of the triangle using Heron’s formula, we need three sides; a, b, c be the three sides of the triangle.

Let’s find out the implementation of the program.

#Python Program to calculate area of triangle using Heron's formula s1 = float(input("Enter first side value: ")) s2 = float(input("Enter second side value: ")) s3 = float(input("Enter third side value: ")) # semi-perimeter s s = (s1 + s2 + s3) / 2 area_triangle = (s * (s-s1) * (s-s2) * (s-s3)) ** 0.5 print("The area of the triangle is: ",area_triangle)

OutputEnter first side value: 5 Enter second side value: 6 Enter third side value: 7 The area of the triangle is: 14.696938456699069

In the above program

- We took input from the user for each of the sides.
- Then we calculate the semi perimeter of the triangle.
- Then we applied
**Heron’s Formula**.

## 3. Calculating the Area of Right angled traingle

Let’s consider a triangle that has one right angle and the **base (b) and height(h) **are provided. Let’s calculate the area of this triangle.

base = int(input("Enter the base: ")) height = int(input("Enter the height: ")) #Float Division area= (base*height)/2 print("\nArea of the right angled triangle is: ",area)

OutputEnter the base: 8 Enter the height: 6 Area of the right angled triangle is: 24.0

## 4. Conclusion

In this article, we have covered how to find the area of the triangle using Heron’s formula and also the area of any right-angled triangle.
