0 - 2 = -2
Answer:
280.6 
Step-by-step explanation:
<u>find the length of each side:</u>
you're only given h = 9 m
the formula for h is
, where a is a side length of the hexagon
plug h in:

a ≈ 10.392 m
<u>now find the area of a triangle:</u>
1/2 (10.392)(9) = 46.764 
multiply that by 6 and you get 280.584 ≈ 280.6 
you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6:
