# C - Write program to calculate area of a room

## Requirements

Read input from user for the length and width of a room in feet and inches.

Then calculates and outputs the floor area in square yards with two decimal places after the decimal point.

## Hint

There are 12 inches in a foot and 3 feet in a yard.

## Demo

```// Exercise 2.2  Calculating the area of a room
#include <stdio.h>

int main(void)
{
double length = 0.0;                     // Room length in yards
double width = 0.0;                      // Room width in yards
long feet = 0L;                          // A whole number of feet
long inches = 0L;                        // A whole number of inches
const long inches_per_foot = 12L;
const double inches_per_yard = 36L;

// Get the length of the room
printf("Enter the length of the room in feet and inches - whole feet first: ");
scanf("%ld", &feet);
printf("                                           ...Now enter the inches: ");
scanf("%ld", &inches);
length = (feet*inches_per_foot + inches)/inches_per_yard;

// Get the width of the room
printf("Enter the width of the room in feet and inches - whole feet first: ");
scanf("%ld", &feet);
printf("                                          ...Now enter the inches: ");
scanf("%ld", &inches);
width = (feet*inches_per_foot + inches)/inches_per_yard;

// Output the area
printf("The area of the room is %.2f square yards.\n", length*width);
return 0;/*from   w w w .ja  v a2 s  .  co m*/
}
