Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
The y-coordinate is between -1 and -2. It is close to halfway between -1 and -2, but it is a little less than halfway.
Answer: Choice B. 
The area of a regular polygon<span> is given by the formula which is expressed as:
</span>area = (½)(apothem<span>)(perimeter)
</span>
We calculate as follows:
area = (½)(7<span>)(7.2 x 5)
</span>area = 126 square units
Hope this answers the question.
