In this post, we will learn** how to find the area of a trapezium using C** Programming language.

A** Trapezium** is a quadrilateral having two parallel sides of unequal length and the other two sides are non-parallel.

**Area of Trapezium = ½ x (Sum of Parallel Sides) x Distance Between Them**

We will be using this formula in our program to compute the area of trapezium

So, without further ado, let’s begin this tutorial.

**C Program to Find Area of Trapezium**

// C Program to find Area of Trapezium #include <stdio.h> int main(){ int b1, b2, height; float area; // Asking for input printf("Enter Base One: "); scanf("%d", &b1); printf("Enter Base Two: "); scanf("%d", &b2); printf("Enter the height: "); scanf("%d", &height); // Calculating area of trapezium area = 0.5 * (b1 + b2) * height; // Displaying output printf("Area of Trapezium: %.2f", area); return 0; }

**Output**

```
Enter Base One: 15
Enter Base Two: 25
Enter the height: 40
Area of Trapezium: 800.00
```

**How Does This Program Work ?**

int b1, b2, height; float area;

In this program, we have declared some** int data type **variables and one **float data type **variable.

// Asking for input printf("Enter Base One: "); scanf("%d", &b1); printf("Enter Base Two: "); scanf("%d", &b2); printf("Enter the height: "); scanf("%d", &height);

Then, the user is asked to enter the value of the two bases and the distance between them.

// Calculating area of trapezium area = 0.5 * (b1 + b2) * height;

We calculate the area of the trapezium using the formula:

**Area of Trapezium = ½ x (Sum of Parallel Sides) x Height**

// Displaying output printf("Area of Trapezium: %.2f", area);

Finally, the result is displayed on the screen using** printf() **function.

**Conclusion**
