We''ll use $100 and $200 for the investment amounts.
Using the attached formula,
Years = natural log (200 / 100) / .12
Years = natural log (200 / 100) / .12
Years = 0.69314718056 / .12
Years =

The formula for sum of the interior angles is,
S = 180 x (n - 2)
and that of the number of diagonals is,
d = n x (n - 3) / 2
where n is the number of sides. For 6-sided polygon,
S = 180 x ( 6 - 2) = 720
d = 6 x (6 - 3) / 2 = 9
Therefore, the answer is 720 degrees and 9 diagonals.
