In the figure below, line T is tangent to the graph ofy=1/x² at point P, with coordinates(w,1/w²), wherew>0. Point Q has coordinates(w,0). Line T crosses the x-axis at point R, with coordinates (k, 0).

Suppose that w is increasing at the constant rate of 5 units per second. When w = 2, what is the rate of change of the area of triangle PQR with respect to time? Determine whether the area is increasing or decreasing at this instant.
