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 formulae for the area will depend on whether or not the octagon is regular.
Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)
An octagon is a square with the corners cut off, so it has 8 equal sides and all angles are the same, like an American Stop sign. If each edge of an octagon is 1 foot, then the area is 4.828 square feet (2+2root2). For an octagon with an edge length of x feet, the area would be 4.828 times x squared.
First of all, you did not provide measurements for the octagon. Second, surface area is meant for three-dimensional figures. Octagons are two-dimensional.
The answer depends on their sizes! A small square will have a smaller area but a huge square will have a bigger area. Do the two shapes have equal sides, apothems, diagonals? Also, a square is a regular shape, what about the octagon?

Multiply all areas of the side times the width
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.
The area of an octagon that has a side length of 2.45m is about 29m2
Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)
the area is 8
Simple the Perimeter you just add the outside numbers. For area. When I look at an octagon I see a rectangle and two Trapezoids on either side of the rectangle. So find the area of each object then add the areas up and voila you got the area of a rectangle.
The area of an octagon with sides of 14 units each is 946.37 units2
If an octagon has a height of 17' and a base of 13'6" then it is not a regular octagon. In that case, a lot more information is required before its area can be calculated.
You don't find the "volume" of a flat figure. Perhaps you want its surface area.The area for a regular octagon of side "a" is 2 (1 + root(2)) a2, where "root" isthe square root function. If it is not a regular octagon, I don't think there is asimple formula to find the area - you'll have to split it up into simpler figures,for example triangles.==================================Answer #2:Here is the formula, to which the first answer alluded in passing,but which, for some reason, it did not explicitly present:Volume of an Octagon = 0 .
To find how many square feet are in an octagon you basicly just have to find the area of the octagon in this problem it would be 8x8 to get the answer how to find the answer is that you must first find out how many sides your shape has then multiply your sides length in this case it happens to be 8 for both of the multiples thus 8x8 equals 64.
