a uniform wire of resistance 1 ohm/cm is bent so as to form letter A of side 20 cm each.if a cross wire of length 10cm is joined so as to form an apprx. angle of 60 degree.find the net resistance b/w the 2 free ends of A.

Its easy.
See the figure.
Drawing-2 :The 2 resistors in the peak of 'A' are in series.
Drawing-3 : 20 and 10 ohm are is parellel.
So, net resistance = 80/3
