A contract worth remembering…
# regular-polygon :: Number, Number, String, String ‑> Image
# Takes in a size, the number of sides, a color, and a fill type and makes a shape with all equal sides and all angles congruent.
Directions: Zora’s favorite shape is a regular pentagon and they want to decorate a special box with pentagons of every color. Help them to realize their dream by writing a function r that takes in a color and returns a solid 5-sided regular polygon of size 300 in the given color.
