1. Answer:

   4 feet

   Step-by-step explanation:

   Let x be the length of the side of the square, in feet.  The new square has sides that are (x – 4) feet,

   The perimeter of the new square would be 4(x – 4) feet.  We are told this new perimeter is 32 feet, so we can write:

     4(x – 4) = 32 feet

     4x – 16 = 32 feet

   4x = 48 feet

    x = 12 feet

   The original sides were 4 feet each.
