Best ResponseYou've already chosen the best response.1Hint: Area of similar polygons are proportional to the square of the linear dimensions (such as a side). A polygon with a side 5 times as long has an area of 5^2=25 times the smaller polygon.

Best ResponseYou've already chosen the best response.1It would definitely been beneficial to learn how to calculate the apothem and the length of the side given the area and number of sides. It would be a little long though.
