A regular nonagon has an apothem that is 15 inches in length. One of the sides has a length of 10 inches. What is the area of the nonagon

A 675 square in
B 712 square in
C 671 square in

Respuesta :

I think it could be "A" only because if one side is 10 inches and a regular nonagon is 15, there is no way it could have a 2 or a 1 in the ones place.
I also believe the answer is A.
