b) A square

Answer 1

a) an equilateral triangle = 600/3
=200 cm
b)a square =600/4
=150cm

Answer 2

We are given Piece of wire= 600cm
 
a) If wire is used to make equilateral trngl. then 
                                Perimeter of triangle=600 cm
                                   So , Side=200cm

b) If wire is used to make square then
                              Perimeter of square=600cm
                                      4*side=600cm
                                         side=150cm
