OpenStudy (kendricklamar2014):

Formula for the Area of an Equilateral Triangle: \[A = \frac{ \sqrt3 }{ 4 } a^2\]

OpenStudy (kendricklamar2014):

Substitute a with 68:\[A = \frac{ \sqrt3 }{ 4 } 68^2\]

OpenStudy (kendricklamar2014):

\[A = \frac{ \sqrt3 }{ 4 } 68^2 = 2,002.25\]

wont let me put it in

OpenStudy (kendricklamar2014):

We have to round to nearest square centimeter

OpenStudy (kendricklamar2014):

So the answer would be: 2,002
