The length of a rectangle is 3 times the width. Not sure how to set this up?

The length of a rectangle is 3 times the width. If the perimeter is to be less than or equal to 104 meters. What are the possible values for the width?

Not sure I know how to set this formula up?

Thanks for your help, but no need to make me feel worse than I do already having to need help or even ask.

That I get, it was the telling me to get off my ass is the part I took as you being rude, but guess that was a nice way of talking for you

I just really hate that this math is so confusing to me at times. I have spent two weeks on trying just to learn one section.

I thought the question was wanting it in a form I had not seen before, but now thanks to you I see that it is not.

The content in the quote box immediately above is a good hint. The perimeter can vary,
then so can the width and the length.

$\displaystyle 0 \ < \ 2(w) \ + \ 2(3w) \ \le \ 104$

Continue.

Thanks I was able to finally find one I could solve, it's just the "new signs" are getting me confused, and now the new ways of when to use ( ) and [] (] [)

Geeeshhhh Joe, my own mother used to tell me that!

If you get off your ass(!) and draw a rectangle,
label short side w (then long side = 3w),
you can tell right away that perimeter is 8w...right?

Awe, okay so it runs in the family. I will remember that in the future if I get help from you again
