You can put this solution on YOUR website! The description switches directions of the dimensions, but doing that makes the description distracting. Both the room and the carpet are twice as long as they are wide.
x, a factor to help relate "length and width" for the carpet, also for the room.
x and 2x are the dimensions of the carpet, for 2x the length, x the width.

You can not really find a value for the carpet area. The room area is not given nor findable; the carpet area is not given nor findable; the border area is neither.

Width of carpet: 6 units
Carpet’s length: 2(6), or 12 units
Carpet’s area: 6(12), or  sq units
