About 19.31cm2
Its perimeter is: 8*6 = 48 cm
The area of the square is the measure of the side squared.
Multiply the length of one side (7 cm) by the number of side (8) to see that the perimeter is 56 cm. This works because a regular octagon has 8 sides of equal length..
The perimeter of an octagon that has one side of 2 inches is 16 inches.

It depends how long each side is. An octagon's sides do not have to all be the same length, they can vary from octagon to octagon. A regular octagon's sides are all equal so the sum of their measures would be 8 times the length of any one side..

The formula for the area of a regular octagon is:A = 2 (1+ SQRT(2)) s**2 , orA = 4.8284 s**2where A= the area of the octagon, ands is the length of one side s**2 indicates s squared or s times s
The area of square is : 36.0
Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)

By Apothem LengthThe area of a regular octagon can also be computed using its measured apothem (a line from the center to the middle of any side). The formula for an octagon with side length s and apothem a is Area = a4s (apothem times one-half the perimeter)So for this example, (7 cm and 8.45 cm) Area = (8.45)(28) = 236.6 cm2----By Side LengthThe area of a regular octagon with side length s is given as Area = 4.828427 s2 , so for a regular octagon of side length 7 cm , the area is also about 236.6 cm2.(This formula is generated by adding or subtracting the missing corner triangles.)
The perimeter of an octagon that has one side of 2 inches is 16 inches.
perimeter of octagon is 128 cm= 8 * side side of the octagon=128/8=16 cm
Each side measures 15. Divide the known surface area by 6... this gives you the area of one side. The square root of the area of one side will give you the length of each side.
