perimeter of a rectangle is 36 meters. 
the <u>length of the rectangle is 4 meters longer than the width</u> {{{highlight_green(w)}}}
find the length and width of the rectangle.   
Question states*** 2l + 2w = 36m
 2(w+4m) + 2w = 36m
 2w + 8 + 2w = 36m
     4w = 28m
      w = 7m, the width and the length is 11m   (7m + 4m)
CHECKING our answer***
 {{{2(11m) + 2(7m)}}} = 22m + 14m =  36m
