measure each edge and times it by eight.
The perimeter of a octagon is the sum of all its sides.
Divide the perimeter by eight.
perimeter of octagon is 128 cm= 8 * side side of the octagon=128/8=16 cm
If a regular octagon has a perimeter of 40cm, then each side is 5 cm.
Providing that it is a regular octagon with 8 equals sides then its perimeter is 8 time 8 = 64 cm
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.
80ft
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 56.
Just add its 8 sides together in meters
It is the sum of the lengths of the octagon's eight sides.
