Answer Document

• 1 x 2424 24 x 124 2 x 1224 12 x 224
• 3 x 824 8 x 324 4 x 624 6 x 424
• I did notice similarities between my different
  arrays. I noticed that 3 rows of 8 is the same
  as 8 rows of 3. This shows the commutative
  property of multiplication. These problems have
  the same numbers as factors they are just
  switched around.
• ANSWERS MAY VARY
• I feel that 4 rows of 6 would give you the best
  set up to watch the career speakers. This way
  there are only 4 rows, so no one would have to
  set too far back. There would only be 6 in each
  row, so no one would be too far to the side of
  the speaker.
