#### Area of rectangle formula

Where l is length and w is width of the rectangle.

#### Logic to find area of rectangle

Below is the step by step descriptive logic to find area of rectangle -

Input length and width of rectangle. Store it in two different variables say length and width.

Apply formula to calculate rectangle area i.e. area = length * width.

Finally, print the value of area.

#### Program to find area of rectangle

```
/**
* C program to find area of rectangle
*/

#include <stdio.h>

int main()
{
float length, width, area;

/*
* Input length and width of rectangle
*/
printf("Enter length of rectangle: ");
scanf("%f", &length);
printf("Enter width of rectangle: ");
scanf("%d", &width);

/* Calculate area of rectangle */
area = length * width;

/* Print area of rectangle */
printf("Area of rectangle = %f sq. units ", area);

return 0;
}
```

##### Output:
```
Enter length of rectangle: 5
Enter width of rectangle: 10
Area of rectangle = 50.000000 sq. units
```
