Question

how do I solve this?

Answer 1

that line is the apothem right?

Answer 2

i think there's a straightforward formula involving the apothem

Answer 3

what is that formula?

Answer 4

found it \[\text{area} = A^2 n \tan (\frac{180}{n})\]
where A is apothem
n is the number of sides

Answer 5

so in your case it's \[\text{area} = (10)^2 (6) \tan (\frac{180}{6})\]
got it?

Answer 6

yes thank you
