Expert Answer:

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
