Hi,
<img src='http://img585.imageshack.us/img585/479/rectangle.png' border='0'/></a>
the width of a rectangle is 2 meters less than the length'x', the area is 48m^2
A = {{{lw = x(x-2) = 48m^2}}}
  x^2 - 2x - 48 = 0
 (x-8)(x+6) = 0, x = 8  (throwing out negative solution for unit measure
Rectangle is 8m  by 6m  (x-2m)
