Where's Peter?

[LiwuyouUE]

Someone asked, "Where's Peter?" Should I answer “He went to the teacher's office.” or "He has gone to the teacher's office"? What's the difference between them?
Moreover, what's the difference between "I've been there before" and "I've gone to there before"?

(Also, may I ask if 'The Greens' is singular or plural?)

Welcome to the forum, LiwutouUE.

We only answer one question per thread, so I've faded out the other two.

Note, too, that I've changed your thread title. Titles must include some or all of the words or phrases you're asking about.

Thank you! I've never asked someone a question in UsingEnglish before... I'm sorry for the inconvenience I caused.

Someone asked me, "Where's Peter?" I responded by saying, "He went to the teacher's office." The other one might be possible in the right context, but nothing readily occurs to me.

Either is possible.

Bear in mind that native speakers often answer questions with the fewest possible words.

Where's Peter?
In the teacher's office.
