The length is 3m more than the width.
 Let x and (x+3m) represent the width and length respectively
Question states***
  2(x+3m) + 2x = 70m
        4x = 64m
         x = 16m, the width.  The length is 19m
 
CHECKING our Answer***  
   32m + 38m = 70m
A. &#8730;30, 5, 6, &#9474;-7 &#9474; B. &#9474;-7&#9474; ,5,6, &#8730;30 C. &#9474;-7&#9474;, 5, &#8730;30, 6 D. 5, &#8730;30, 6, &#9474;-7 &#9474;
