## Formula for the Area Of Rectangle

The formula to calculate area of a rectangle is simple and straight forward-

*Area = Length * Width*

Here, Length represents the longer side of the rectangle while Width represents the shorter side of the rectangle.

## C Program to Calculate Area of Rectangle

Let’s write a C program to calculate the area of a rectangle

```
#include <stdio.h>
void main()
{
float length, width, area;
printf("Enter the length of rectangle ");
scanf("%f", &length);
printf("Enter the width of rectangle ");
scanf("%f", &width);
area = length * width;
printf("The area og given rectangle is = %f", area);
}
```

### Output

## How the Above C Program Works?

- The program starts with the declaration of three variables-
`length`

,`width`

, and`area`

of type`float`

. - Then program asks the user to input the length and width of the rectangle.
- The area of a rectangle is calculated by multiplying the
`length`

and`width`

. - At the end, the calculated area is printed.

*Happy Coding*
