How to make such a layout with flex?

Question

css

I just got acquainted with flexbox, but I still don’t know how to make it up. So to say, there are tools, but I don’t know how to use them yet)
The layout is simple, if not difficult, throw off a few options for writing it.

Also, if you know any videos, articles on the practice of flex, I would be very grateful. I didn't find anything good.
