    Answer: 21 rows

    Step-by-step explanation:

    First find out the number of chairs that are currently in the school.

    = 15 rows  * 28 chairs

    = 420 chairs

    If 420 chairs were to be arranged in rows of 20, the number of rows would therefore be:

    = 420 / 20 per row

    = 21 rows
