Which of the following is the perimeter of the inner edge of the frame?

343.56 inches
289.56 inches
258.78 inches
204.78 inches

Answer 1

I got 204.82 the first time I did this one too. I tried it again rounding pi to 3.14 and got 204.78, which means your answer is a little off due to rounding different, so go with 204.78. Basically, you did it right :)
