Perimeter = Length of side 1 + Length of side 2 + Length of side 3 + Length of side 4 + Length of side 5 + Length of side 6 + Length of side 7 + Length of side 8.
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.

If the octagon is not regular, the perimeter could have any value greater than 18 inches. If it is regular, then the perimeter is 8*18 = 144 inches.
To find the area of a regular octagon, you can use the formula: Area = (Perimeter × Apothem) / 2. Given the perimeter is 66.3 inches and the apothem is 10 inches, the area calculates to: Area = (66.3 × 10) / 2 = 331.5 square inches. Rounding to the nearest square inch, the area of the octagon is approximately 332 square inches.
The formula for measuring the area of a square is s2, where s is the length of one of the sides. The perimeter would be 4s.

8*length of side.
Perimeter = 8 x (length of one side)

The perimeter of a octagon is the sum of all its sides.
1/2*h*b
The perimeter of a triangle is the sum of its 3 sides.
The length of a square is not determined by a formula, it is determined by measuring the square.
You add all the sides of the pentagon together.
