#A = (3x^2 -13x+4)m^2#

The length and width are both given in terms of #x#.

The exact area cannot be determined, but we can find an expression for the area of the room in terms of #x#

#A = l xx b#

#A = (3x-1)(x-4)#

#A = 3x^2 -12x-x+4#

#A = (3x^2 -13x+4)m^2#

When the value for #x# is known, the area can be calculated.
