4. In the figure, the area of parallelogram ABCD is
(a) AB x BM (b) BC x BN (c) DC x DL (d) AD x DL

5. In figure, if parallelogram ABCD and rectangle ABEM are of equal area, then

(a) perimeter of ABCD = perimeter of ABEM
(b) perimeter of ABCD < perimeter of ABEM
(c) perimeter of ABCD > perimeter of ABEM
(d) perimeter of ABCD = ½ (perimeter of ABEM)

6. X and Y are points on the side LN of the triangle LMN such that LX = XY = YN.
Through X, a line is drawn parallel to LM to meet MN at Z (see figure). Prove that ar
(ΔLZY) = ar (MZYX).
