    summary: perimeter add the sides
    rectangle length * width
    square area: a* thats a square.

    (Upvote this comment) For all the people thinking about dropping out, don't. I dropped out back in 2016 during my freshman year and I'm currently doing this math at 20. Over time, lack of education deteriorates your math skills and right now I'm having to re-learn everything all the way up to geometry. For easier study methods I recommend looking up the Pomodoro system, it's quite tremendously paved my success in independent studying. Let me know if it helped you too!.
