Perimeter of Square = Circumference of the circular wire.
4a = L ........... a - side of square; L - circumference of the circular wire or length of the wire.
a = L/4
RCirWire = ρL/A;
ρ/A = RCirWire/L
Redge = ρa/A,
where A is the cross sectional area of wire and will not change.
Redge = ρa/A =a RCirWire/L = 6/4 = 1.5 Ω
