Is there a perimeter and area in every shape?

Answer 1

yes, except for a circle. the name of a circles perimeter is called circumference and it basically a perimeter but since its rounded instead of box like it not called perimeter but other then that yes.

but there are many different methods to finding each one and trying to find out each of those methods would be insanely difficult, and take years to learn, not to mention that there is probably shapes that we've never even heard about or seen
