If you know a side length, s, the perimeter is 8 s
If you know the circum radius, r, (the distance from the center to a vertex) , the perimeter is
p = 8 r sqrt(2 - sqrt(2)) (approx 6.12 r)
If you know the apothem, a, (the distance from the center to the middle of a side),
p = 16 a sqrt(2-sqrt(2))/sqrt(sqrt(2)+2) (approx 6.63 a)

How do you find the sides of an octagon with perimeter?
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.

The perimeter of this regular octagon is 56 How long is each side?
To find the length of each side of a regular octagon with a perimeter of 56, we divide the perimeter by the number of sides. Since an octagon has 8 sides, we divide 56 by 8 to get 7. Therefore, each side of the regular octagon is 7 units long.
Is the perimeter of an octagon 64?
