Translation: He is one hundred years old.

[Lingvamanto]

So in order to say someone's age, we use the typical for Romance languages structure "to have [amount] years" (a avea ... (de) ani), don't we?

[Caesar_Imperator]

Yes, you are correct.

[avrildowds]

In English it is correct to say that someone is not has.. Years old

[Jadenutt]

in some of the other similar exercises, the correct answers suggest number+ani without de, i am wondering what is going on

[Spacekh]

What I've gathered from other comments: 20+, add de. Under 20, no de.
