Answer:

No diagram and no explanation what 9 is.

However, if it is an octagon with each side equal to 9 then

area = (# of sides * side^2) / (4 * tan (180 # of sides))

area = 8 * 9 * 9 / (4* tan (180 / 8)

area = 648 / 4 * 0.41421

area = 391.1059607446

answer is C

Which pair represents equivalent ratios? A Begin fraction . . . 2 over 3 . . . end fraction . . . and . . . begin fraction . . .

Blizzard [7]

Equivalent ratios are those ratios which are same that is on simplifying each of them, we will get the same answer.

A. $\frac{2}{3} and \frac{9}{15} = \frac{3}{5}$

So they are not equivalent

B. $\frac{5}{8} and \frac{15}{21} = \frac{5}{7}$

So they are not equivalent

C. $\frac{3}{12} and \frac{6}{18} = \frac{1}{4} and \frac{1}{3}$

They are not equivalent too.

D. $\frac{4}{10} and \frac{12}{30} = \frac{2}{5} and \frac{2}{5}$

And they are equivalent. SO the correct option is D .
