Answer:
its the third one i got that
It is 31%.
To explain, you have to just have to multiply 0.31 by 100, and then add a percentage sign.
Well if the perimeter is 36in, then divide by 6 sides (the prefix hex- means six) to get 6. Don't forget your unit of measurement to be 6in of each side. It would be nice to have the picture though so if you could suply me with that it would help out.
I would need to have the same book and go to page 73 to be able to answer it. By the way, do you have any friends that have the answer?
