How to determine the area of a regular hexagon

The video tutorial explains how to calculate the area of an irregular polygon using the formula 1/2 * a * p, where 'a' is the apothem and 'p' is the perimeter. The teacher defines the apothem as the distance from the center to a side and demonstrates calculating the perimeter of a regular hexagon. The tutorial concludes with applying the formula to find the area, resulting in 144 square feet.

If a regular polygon has 6 sides and each side measures 8 units, what is the perimeter?

What are the units of measurement for the area calculated in this problem?
