Calculating the area of a room

int main()

{

  double length = 0.0;

  double width = 0.0;

  long feet = 0L;

  long inches = 0L;

  const double inches_per_yard = 36L;



   feet = 9;

   inches = 11;

   length = (feet*inches_per_foot+inches)/inches_per_yard;



   feet = 20;

   inches = 3;

   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);
