Octagon: 8 sides; each side 12 cm; 12 x 8 = 96 cm
It is the sum of the lengths of the octagon's eight sides.
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
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.
12cm (4 sides x 3 = 12)
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.
The perimeter of a octagon is the sum of all its sides.
It is the sum of the lengths of the octagon's eight sides.

With 3cm for each sides.
The perimeter is 56.
12cm (4 sides x 3 = 12)
Providing that it is a regular octagon with 8 equals sides then its perimeter is 8 time 8 = 64 cm
22cm
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.
It is the sum of its 8 sides
32cm.
