## C Program to Calculate area of right angle triangle

### Introduction

Welcome to our comprehensive guide on calculating the area of a right-angled triangle. In this article, we will provide you with a step-by-step approach to accurately determine the area of a right-angled triangle. By following the methods outlined below, you will gain a solid understanding of this calculation and be able to apply it effectively in various scenarios.

### Understanding Right-Angled Triangles

A right-angled triangle is a polygon with three sides, where one angle measures exactly 90 degrees, forming a perfect right angle. It is essential to familiarize yourself with the different components of a right-angled triangle before proceeding with the area calculation.

#### Components of a Right-Angled Triangle

**Hypotenuse (H)**: The side opposite the right angle is known as the hypotenuse. It is denoted by the letter “H” and is the longest side of the triangle.**Legs (L1 and L2)**: The other two sides of the right-angled triangle are called legs. They are denoted by “L1” and “L2”.

To calculate the area of a right-angled triangle, we will utilize a simple formula based on the lengths of its legs.

### The Area Formula

The formula to calculate the area of a right-angled triangle is as follows:

`Area = (L1 * L2) / 2`

To obtain the area, multiply the lengths of the two legs and divide the result by 2. This formula holds true for any right-angled triangle, regardless of the specific measurements of its legs.

### Step-by-Step Calculation

To demonstrate the calculation process, let’s consider an example with specific leg measurements:

- Leg 1 (L1) = 5 units
- Leg 2 (L2) = 8 units

Now, let’s calculate the area using the formula we mentioned earlier:

```
Area = (5 * 8) / 2
= 40 / 2
= 20 square units
```

Therefore, for a right-angled triangle with legs measuring 5 units and 8 units, the area is 20 square units.

### Importance of Calculating the Area of a Right-Angled Triangle

The area of a right-angled triangle plays a significant role in various fields, including geometry, engineering, architecture, and construction. By accurately determining the area, professionals in these disciplines can make precise calculations and design plans accordingly.

## C Program to Calculate area of right angle triangle

#include<stdio.h> int main() { double base,height,area; printf("Enter base and height : "); scanf("%lf %lf",&base,&height); area=.5*base*height ; printf("Area of right triangle is:%.3lf",area); return 0; }

**Output:**

### Conclusion

In conclusion, calculating the area of a right-angled triangle is a fundamental mathematical operation with practical applications in various domains. By following the step-by-step approach outlined in this guide, you can confidently determine the area of any right-angled triangle you encounter. Remember to use the formula (L1 * L2) / 2, where L1 and L2 represent the lengths of the triangle’s legs. By mastering this calculation, you will enhance your problem-solving abilities and gain a deeper.
