Hi,
the length of a rectangle is 4 centimeters less than three times its width{{{x}}}. 
If the area is 55 square centimeters, find the length{{{(3x-4)}}} and width {{{x}}}
   x(3x-4) = 55
   3x^2 - 4x - 55 = 0
 (3x + 11)(x-5) = 0
          x = 5, throwing out the negative solution for unit of measure
 width is 5 and length is 11
