An easy way to figure out if the rectangle would work is to add 48-60" to the length and width measurements to allow for chairs and movement. So for your 90 x 44 table, using the industry standard of 30" per chair for pullout and movement then it would equal 150" x 104". Your room is 144" x 144" so it would not work. Go with a 60" round - you can seat 8 easily and 10 if you don't use oversized chairs.
