if the wire is bent in circle the length of the wire become circumference of circle.
circumference of a circle = 2*pi*r
264 = 2*pi*r
pi*r = 264/2
pi*r = 132
pi is approximately equal to 22/7
22/7 * r = 132
r = 132*7/22
r = 42 cm
if the wire is bent in square the length of wire become perimeter of square
perimeter of square = 4 *side
264 = 4*side
side = 264/4
side = 66 cm
