What is the area of a regular hexagon with a side of 5 and an apothem of 4.33

The area of any regular polygon can be expressed as:

a (n, s) = (ns^2) / (4tan (180/n)), where n=number of sides and s=side length

(notice apothem is not needed : P)

a (6,5) = (6*5^2) / (4tan (180/6)

a (6,5) = 37.5/tan30

a (6,5) ≈64.95 units (to nearest hundredth of a unit)

6 · (1/2) ·5· (4.33) = 64.95in²
