# C Program to Find Area of Trapezium

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;

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.
