Solution
The correct option is B86.5 For a regular hexagon with apothem 5m the side length is about 5.77m.
Use the formula A=12pa
to find the area of the hexagon.
The perimeter of the hexagon is about 6(5.77) or 34.62m.
Now substitute the values. A=12(34.62)(5)
Simplify. A=12(173.1)
= 86.5 A=12(173.1)
= 86.5
Therefore, the area of the regular hexagon is about 86.5m2.
