Hello friends

Can I ask how to calculate the perimeter of the rectangle?

Thank you very much

I will tick you first

And if you're right and you're wrong, you won't get a tick

Please don't curse in the comments

And here are the rules

I. Rules of participation "Help me solve math"

1. Do not post miscellaneous questions on the forum, only post articles that they cannot solve or good questions on the forum;

2. Do not answer miscellaneous, inconsistent with the content of the question on the forum.

3. Do not tick "True" on miscellaneous answers to cheat the question and answer points.

If you violate the above 3 things, your online Math teacher will deduct all question and answer points, you may be locked out of your account or permanently banned from logging in to the website.

Readers, please remember

Thank you so much
