Hi,



P = 2%2AL+%2B+2%2Aw+=+42m   0r ****   L + w = 21m

the length of a rectangle is 5 meters more than the width+highlight_green%28x%29

   (x+5m) + x = 21m

         2x + 5m = 21m

          2x = 16m

           x = 8m, the width and the length is 13m

CHECKING our answer***

 21m + 8m =  =21m     0r   26m+ 16m = 42m

Wish You the Best in your Studies.
