Draw lines from one vertex to the other vertices, splitting the polygon into triangles. If the polygon has n sides, there will be n−2 triangles. Each triangle's angles add up to 180°. So the sum of all the interior angles is:

S = (n−2) 180°

Vincent propses an idea to the student government to install a basket hoop along with a court marked with all the shooting lines

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

My answer:

Scale Drawing Lengths: . . / .

Actual Court Lengths . . .

Scale Factor: inch corresponds to ( ∙ ) inches, or inches, so the scale factor is .

Let = , represent the scale drawing lengths in inches, and represent the actual court lengths in inches. The -values must be converted from feet to inches.

To find actual length:

= =

() = inches, or feet

To find actual width:

= = ( )

= / ∙ /

= inches, or feet

The actual court measures feet by feet. Yes, the lot is big enough for the court Vincent planned. The court will take up the entire width of the lot.
