J'ai treize ans, I have thirteen years or

Je suis treize ans, I am thirteen years

If you want to supply the information requested, then

"J'ai treize ans."

But otherwise:,

"À toi, ça ne te regarde pas du tout" (that's none of your business),

Nop, actually it would be "J'ai treize ans."

Even if in English we usually say "I am thirteen years old", in french we use the verb "have".

And yeah, you could also say "Mêle de tes affaires." which means "mind you own business" if you don't want to respond haha.

Hope this helps:)

j'ai treize ans.
