?????????????Construction: Drop a perpendicular h from D on AB
Solution: Area of ||gm ABCD = base X height = AB X h = 280 sq.cm
Given, AP : PB = 2 : 3
So, AP = {2/(2+3)} AB = (2/5)AB
So, area of ||gm APQD = base X height = AP X h = (2/5)AB X h
                                  = (2/5)X 280 = 112 sq.cm
