one way to do it is to first draw a rectangle around the octagon then multiply length by width then subtract the area of the four triangles out side the octagon from your total answer.
OR
You can use the formula A= 2 s2 cot(π/h)
π is supposed to be pi
s2 is supposed to be s squared
Cot is an abbreviation for cotangent

How can you find the area of a shaded region assuming the octagon is regular?
To find the area of a shaded region within a regular octagon, first calculate the area of the entire octagon using the formula ( A = 2(1 + \sqrt{2})s^2 ), where ( s ) is the length of a side. Then, determine the area of any non-shaded regions (such as triangles or smaller shapes) within the octagon and calculate their total area. Finally, subtract the area of the non-shaded regions from the total area of the octagon to find the area of the shaded region.
What is the formula to find the volume of an octagon?
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 .
A regular octagon has an apothem measuring 10 in. and a perimeter of 66.3 in. What is the area of the octagon rounded to the nearest square inch?
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 volume of an octagon?
an octagon doesn't have a volume its has and area ecause it is a 2-d figure. to find the area of a 2-d regular figure it is 1/2 apothem * perimeter (apothem is the distance of a line from the center of a polygon, to the midpoint of a side)
What is the square footage of an octagon house that has 12 feet sides?

How do you find the area of an octagon?
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
