For a square P=4s where P is the perimeter and s is the length of a side.<P>
Divide both sides by 4 to find that P/4 = s.<P>
122/4=s=30.5 inches.  The length and width of a square are the same.  All the sides are the same length.<P>
P=78=4s<P>
Divide both sides by 4<P>
78/4=s=19.5 ft.  Every side of the square is 19.5ft.  The length and width are both 19.5 feet.
