Answer:

Step-by-step explanation:
Let the side length for the octagon having 9m² as area = x
Side length for the octagon having area of 25m² = y.
Thus:
(area of similar polygons theorem)
The scale factor of their sides would be
. Which is:



Scale factor of their sides = 
55x + 10 = 57x....where x = number of months
10 = 57x - 55x
10 = 2x
10/2 = x
5 = x.....they will cost the same at 5 months...they will each cost $ 285 at 5 months
