A square ACBD  has an area of 4.  The square is then dilated with a scale factor of  X producing a square  A'B'C'D' of area  9 Find the sum of all possible values of X?

It is a square.....   the smaller one is   2 x 2  = 4      the larger is 3 x 3 = 9

   so the dilation went from   2 to 3     the scale factor is thus  1.5  = X
