Hi,



P = 2%2Al+%2B+2%2Aw = 500   ⇒   l + w = 250

The length of a rectangle is 9 times its width +highlight_green%28x%29

   9x + x = 250

    10x = 250

      x = 25, the width.  The length is 225

CHECKING our answer***

  25 + 225 = 250    0r    50 + 450 = 500

Wish You the Best in your Studies.
