Triangle XYZ above is similar to triangle UVW (not shown). If the length of one side of triangle UVW is 60, then what is one possible perimeter of triangle UVW?

With the limited information given, the perimeter can be anything over 120.
However, if more information is supplied, such as the angles of UVW or XYZ, we can narrow it down better. 
triangle xyz not shown is smiliar to triangle abc shown above if one side of triangle xyz is 10 inches long, which of the following could be the length in inches of another side of triangle xyz?
