If a polygon has a perimeter of 24, which of the following could be the area of the polygon?

I watched Greg’s solution video for this quiz. He discusses about the smallest area to be that of an equilateral triangle.
However, in this question in quiz, he has changed the word ‘regular polygon’ to ‘polygon’. So here how should I calculate the smallest area possible?

The minimum happens when the polygon is regular.
