Question

Find the area of a regular hexagon with a side of length 15 feet.


545.6 ft2


389.7 ft2


779.4 ft2


337.5 ft2

Answer 1

Break it up into six little triangles. Get area of one and multiply by 6.

Answer 2

You can make a quick approximation by replacing the hexagon with a circle with a circumference of 6 x 15 feet = 90 feet. Then pi D = 90, D = 28.7,
A = (pi/4) D^2 = 644 ft^2. Only two of your options are close. A circle maximized the area within a given perimeter, by the way, another clue.
