For a rectangle, you need to have sides A and B wide and long. Then you multiply A and B to get the 50 players.

This is the same as asking how can 50 be factored into two factors (which don't have to be prime).

Start with the prime factors.

50 = 5 * 10 = 2 * 5 * 5

Um. There aren't a lot of ways, really, to make two numbers from 2, 5 and 5, are there?
