Calculating the area of a room

#include <stdio.h>

int main()
{
  double length = 0.0;
  double width = 0.0;
  long feet = 0L;
  long inches = 0L;
  const long inches_per_foot = 12L;
  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);
}
