Simply add up the length of all 8 sides. If the problem tells you that all sides are equal, you can simply take the length of one side and multiply it by 8.
You say these things to yourself: -- "The perimeter is the distance all the way around the octagon." -- "The octagon has eight sides." -- "So, if it's a 'regular' octagon, then all the sides are the same length, and each side must be 1/8 of the perimeter." -- If it's not a 'regular' octagon, then it has some longer sides and some shorter ones, and the perimeter doesn't help me find the lengths of the sides.
You cannot. The perimeter alone does not provide enough information unless the octagon is regular and there is no valid reason to assume that it is.
It is the sum of the lengths of the octagon's eight sides.
The perimeter of an octagon is 64 only if it is a regular octagon and the length of one side is 8. An irregular octagon may or may not have a perimeter of 64 (whatever units of measure you choose to use) depending on what the lengths of the individual sides are.
The perimeter of an octagon that has one side of 2 inches is 16 inches.
The perimeter of a octagon is the sum of all its sides.
Divide the perimeter by eight.
We searched as far below as possible and were unable to find the octagon.

Perimeter = 8 x (length of one side)

measure each edge and times it by eight.
80ft
Just add together its 8 sides
The perimeter is 56.
If it's a regular octagon, the perimeter is 8 times the length of one side.
It is the sum of the lengths of the octagon's eight sides.
