Points M, N, and O are the midpoints of sides \overline{KL}, \overline{LJ}, and \overline{JK}, respectively, of triangle JKL. Points P, Q, and R are the midpoints of \overline{NO}, \overline{OM}, and \overline{MN}, respectively. If the area of triangle PQR is 27, then what is the area of triangle OPQ?
