**JJ**, Wednesday, February 20, 2013 at 7:14pmAn octagon has 8 sides.

Perimeter = 8 times length of 1 side.

- math -
**andrew**, Wednesday, February 20, 2013 at 7:16pmso is it 8 times x?

8*x?

- math -
**JJ**, Wednesday, February 20, 2013 at 7:17pmno we have p = perimeter

You want to use p and 8.

Do you multiply or divide?

**lina**, Wednesday, February 20, 2013 at 7:19pmoh you multiply?

- math -
**andrew**, Wednesday, February 20, 2013 at 7:19pmYOU MULTIPLY!

right..?

**JJ**, Wednesday, February 20, 2013 at 7:20pmno, you would divide.

Let's say the perimeter is 40?

Would it make sense to say a side is 320

or does it makes sense to say a side is 5?

- math -
**andrew**, Wednesday, February 20, 2013 at 7:21pmthat makes sense so it would be 8/p then?

- math -
**JJ**, Wednesday, February 20, 2013 at 7:22pmNO.. p/8

40/8

- math -
**andrew**, Wednesday, February 20, 2013 at 7:24pmOhhhhh that makes much more sense thank you so just p/8 or p/8=x ?

- math -
**JJ**, Wednesday, February 20, 2013 at 8:09pmRight. Glad it makes sense.
