Answer 2

HI!!

Answer 3

looks like the formula is \[A=\frac{\sqrt3}{4}a^2\] in your case \(a=3\)

Answer 4

you got that?

Answer 5

I don't quite understand, how would the area be 3?

Answer 6

the area is not 3, the side is 3

Answer 7

oh okay

Answer 8

so the area is
\[A=\frac{\sqrt3}{4}\times 3^2\]
