Let the width of the rectangle = x
Given, the length is 2 m more than twice the width.
So the length = 2x+2
Perimeter is 2(2x+2+x) = 142
               (3x+2)  = 142/2
                3x+2 = 71
                3x = 71-2
                3x = 69
                 x = 69/3
                 x = 23m
Therefore width = 23 m
          length= 2x+2 = 2*23+2 = 48m</PRE>
