Answer 1

How do you do this, @AaronAndyson?

Answer 2

Area of an equilateral Triangle =
\[\frac{ \sqrt 3 }{ 4 }a^2 ; a = 68\]

Answer 3

2002

Answer 4

Wait...

Answer 5

Don't you do square root of 3 first?
then square root of 3 divided by 4
then multiply 68^2?

Answer 6

that's how i got 2002

Answer 7

Yes,2002.25 cm^2 is the right answer :)

Answer 8

\[\frac{ \sqrt3 }{ 4 }a^2\]
\[\frac{ \sqrt3 }{ 4 }68^2\]
\[\frac{ \sqrt3 }{ 4 }*4624\]

Answer 9

So thats sqrt 3 times 1156

Answer 10

sqrt 3 = 1.732

1.732*1156 = 2002.25

Answer 11

Ahhh...
Thanks! :)

Answer 12

Since it says "Nearest square centimeter" so we just leave it as 2002 :D
