You need to learn how to use a ductulator. You can pick these up at a local sheet metal supplier. There are other factors also ie; heat and cooling loads, the number of people for fresh air requirements,static pressure. But I'll assume this is just a test question from your boss. Any supply house will gladly show you how to use one, not hard to do, good luck.

heat gain / loss will need to be known to determine unit size then comes duct sizing
