    7.  If the  base  and  height  of  a  triangle  and  the     9.  A scalene triangle is given, and two straight
                         length and breadth of a rectangle are equal,        lines  are drawn inside  it  in  any  direction.  If
                         what can you  say  about  the  areas  of both       the triangle is divided along these two lines,
