You can put this solution on YOUR website! w = breadth of original room;
L = length of original room;
L=w+3.
Original room
w and L, area is wL.
New room
L+3 and w-2, area is (w-2)(L+3).
The two rooms were equal area. The two equations for this system are  and from the written problem description,  . Substitution for L allows to solve first for w.
