A point PP moves along the curve y=ln(x)y = \ln(x). Let AA be the area of the rectangle formed by the origin, the point (x,0)(x, 0), the point (x,lnx)(x, \ln x), and the point (0,lnx)(0, \ln x). If xx is increasing at a constant rate of 22 units per second, determine the rate of change of the area AA with respect to time tt at the instant x=ex = e.
