The area of an equilateral triangle can be calculated using the formula: (s^2 * sqrt(3))/4, where s is the length of a side.

In this case, the side of the triangle is 8√3 m. Plugging this into the formula:

Area = (8√3)^2 * √3 / 4
Area = 64 * 3 * √3 / 4
Area = 192√3 / 4
Area = 48√3

Rounding to the nearest whole number, the area is approximately 83 m2.

Therefore, the correct answer is 83 m2.
