Answer:

31.177 m

Step-by-step explanation:

So the formula of a hexagon is Area = (3√3 s^2)/ 2

s = side in this problem. A hexagon is made up of 6 equilateral triangles, so the distance from the center is equal to each of the sides.

For this problem, plug and chug. Plug your knowns into equation and you will find the answer.

s^2 = (2√3)^2 = 12

Area = (3√3 x 12)/2 = 31.1769 m

I am not sure how many decimals you are supposed to round, probably 3 so in that case 31.177 m
