Hello
you asked the same question as on this thread.

How to adjust the proportion of squares

[1] We created a square with a ratio of 0.25% of a particular square. I hope the newly created square will be 1:1 instead of the width-width ratio of the existing square. How can I adjust it? Thank you in advance.

I would be polite if you told me why my answer was not good.
