Just add together its 8 sides
If it's a regular octagon, the perimeter is 8 times the length of one side.
The perimeter is 72.
Perimeter = 8*15 = 120 cm
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.

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.
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.
Perimeter = 8 x (length of one side)
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.
measure each edge and times it by eight.

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.
