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.
It is the sum of the lengths of the octagon's eight sides.
By using the definition of "perimeter": you need to add the lengths of all eight sides. If it is a REGULAR octagon, you multiply the length of any side by 8, since all sides have the same length.
The perimeter of an octagon is the distance around its outside, so it is the sum of the lengths of each of its eight sides.
32cm.
8 (measure of each side) x 8 (total sides of an octagon) = 64cm
The perimeter of a octagon is the sum of all its sides.
Just add together its 8 sides
8 sides x 5.5 = 44
It is the sum of the lengths of the octagon's eight sides.
Just add its 8 sides together in meters
The perimeter is 56.
Providing that it is a regular octagon with 8 equals sides then its perimeter is 8 time 8 = 64 cm

920 mm. Because since an octagon has 8 sides and they are all 115 in length, to find the total perimeter simply add up 115 8 times, or multiply 115 by 8.
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.
The perimeter of an octagon is the distance around its outside, so it is the sum of the lengths of each of its eight sides.
