Expert Answer:

If the wire is in the shape of square,
that means length of all the 4 sides will be equal.
Perimeter of a square is the sum of all the 4 sides = 60cm
Length of each side = 60/4 = 15 cm
 
If the same wire is bent to a regular pentagon,
the perimeter will remain the same.
 
A regular pentagon has 5 sides of equal length,
thus, the length of each side will be
60 / 5 = 12 cm
