Does copying facts from Wikipedia, with attribution, constitute plagiarism?
I'll assume the quotation marks were used in the advertisement.  Since you represented the text as coming from the reference, and provided the reference, it's not plagiarism.

That doesn't mean it's necessarily okay.

If the purpose of the assignment was to practice writing advertisement text, then you didn't do that and didn't complete the assignment.

If the purpose of the assignment was to practice graphical design, you might have done that, and the text might be okay.

In any case, ask your instructor what they want you to do before you submit your assignment.
