The area would be about 83.14.
You can find this by starting with the formula for the area of an equilateral triangle:
A = [tex] \frac{\sqrt{3}}{4} S^{2} [/tex]
In this equation, A is the area and S is the side. So we'll just plug in the value.
A = [tex] \frac{\sqrt{3}}{4} S^{2} [/tex]
A = [tex] \frac{\sqrt{3}}{4} (8\sqrt{3})^{2} [/tex]
A = [tex] \frac{\sqrt{3}}{4} 24 [/tex]
A = 83.14
