Adsense disapproval

Hello everybody, hope you are doing great!!

I started a blog a month ago with 9 years old domain, but i used blogger for free hosting. Now I have more than forty articles (200 till 400 words). Also, I use a free template, and I receive 100/200 visitors daily.

Please tell what i need to have my AdSense approved because it's getting frustrating.
thank all in advance.
