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
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 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

Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)

A regular octagon is a polygon with 8 sides of equal length. To find the area of a regular octagon with a side length of 24 cm, we can use the following formula: Area = (8 × side^2) / (4 × tan(π/8)) where side = 24 cm Plugging in the value, we get: Area = (8 × 24^2) / (4 × tan(π/8)) Area ≈ 736.44 cm^2 So, the area of the regular octagon is approximately 736.44 square centimeters.
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 .
