A carpet whose length is 1(1/6)
times its width is laid on the floor of a rectangular room, with a margin of 1 foot all around. The area of the floor is 4 times that of the margin. Find the width of the room.

• 12 ft
  
  If w is the width, then
  
  
  4*( (w+2)*(7/6 w +2) - 7/6 w^2)= (w+2)*(7/6 w +2)
  
  solving it, we get
  w=12 ft
