These two regular octagons are similar. So, the theorem we used on the previous problem holds here. The square of the scale factor of two similar polygons is equal to the ratio of their areas.

In words, the proportion is: the square of (one is to eight) = 35 to x where x is the area of the octagon that has sides of length 8 times the sides of the smaller octagon.
