The area of an octagon with each side being 8 feet is 309 square feet.
The formula for the area of an octagon is Area = (2 + 2√2)a2, where a is the length of each side. Area = (2 + 2√2)12ft2 = 695ft2
Start with one octagon.Place an octagon along every other side of the first octagon. This creates square gaps which can be filled using the squares. At this stage the general pattern should be evident.
The answer depends on whether or not the octagon is regular and also on what information about its side lengths, angles, etc you have.

The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.

We know that an octagon is an eight-side polygon. Since each side has the same distance form the center of the circumscribed circle of the octagon, this octagon is a regular octagon. If we draw the radii of the circle (their endpoints there are at the vertexes of the octagon), we form 8 isosceles triangle, which radius represents two their congruent sides with a measure of 7.5 cm, and the distance drawn from the center of the circle to the sides of the octagon represents their altitudes with a measure of 6.9 cm. So, by using the Pythagorean theorem we can find the half of the side of the octagon, which is: 7.5)^2 - (6.9)^2 = 8.64 Since one half of the octagon side is square root of 8.64, the whole side is 2(square root of 8.64) Thus the perimeter of this octagon is approximately 47 cm [8 x 2(square root of 8.64)].
If each side of the square is 20-ft, then the area of the square is (20 x 20) = 400 square feet.
The average square footage of a 2 bedroom house is around 1600 to 2400 square feet. Most two bedroom houses are built on the small side.
Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)
Take the length of one side and square it. For example, if the side is 2 feet, then 2 squared (the number times itself) equals 4 feet.

Cut the corners off of a square or rectangle, but do so from points that are not near the centers of each side.
