An octagon has 8 sides.
Perimeter = 8 times length of 1 side.
so is it 8 times x?
8*x?
no we have p = perimeter
You want to use p and 8.
Do you multiply or divide?
oh you multiply?
YOU MULTIPLY!
right..?
yes
no, 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?
that makes sense so it would be 8/p then?
NO.. p/8
40/8
Ohhhhh that makes much more sense thank you so just p/8 or p/8=x ?
Right. Glad it makes sense.
