<p>@eharr3 Rats… Thanks. I think that’s the one. I eliminated three of the choices so I figure I’d guess. One remaining question I need answered: Was 37.5 the answer to the polygon inscribed in the square question on section 9? (I calculated the area of the square, broke the square into four equal triangles, and then broke the triangles into eight equal pieces of 12.5.)</p>
