Let x represent the width, then x + 2 represents the length, in other words the two legs of the right triangle formed by the diagonal.

So:

Discard the negative root because we are looking for a positive measure of length. Width is 6, Length is then 6 + 2 = 8. You can calculate the perimeter for yourself.
