A rectangle's length{{{highlight(L)}}} is 3 more than three times its width{{{highlight(W)}}}
 finding the Dimensions is to find the length and width
  2L + 2W = 110cm
   L + W = 55cm       {{{L = 3W+3}}}
 3W +3 + W = 55cm
      4W = 52cm
       W = 13cm   and L = 42cm    and   {{{26cm + 84cm = 110cm = P}}}
 A = L•W = 13cm•42cm = 546cm^2
