Question 50639
If he fences in the square that would be 4 equal distances (sides).  If he subdivides this square to divide it into four smaller squares, then that would be two additional sides each side being equal to the four sides of the square.  This means that he has fenced a total of 6 equal distances of fence amounting to 480 feet.  Divide the 480 feet by 6, and that means that each side of the large square will be 80 feet.  The total area of this square will be {{{80^2= 6400 }}} square feet or 6400 ft. squared.
