Okay, the answer A=3 4a2=3 4·1432≈8854.67674

uhm. The answer choices are 1) 85 ft^2 2) 170 ft^2 3) 255 ft^2 4) 510 ft^2

OpenStudy (sleepyhead314):

Area of equilateral triangle = sqrt(3) * (side)^2 / 4

OpenStudy (sleepyhead314):

\[Area = \frac{ \sqrt{3} }{ 4 }*(side)^2\]

OpenStudy (sleepyhead314):

\[Area = \frac{ \sqrt{3} }{ 4 }*(14\sqrt{3})^2\]

OpenStudy (sleepyhead314):

\[Area = \frac{ \sqrt{3} }{ 4 }*(588)\]

OpenStudy (sleepyhead314):

\[Area = \sqrt{3} * 147\]

= 254.6114687126249484
