The area of an octagon with each side being 8 feet is 309 square feet.
44499 sq ft (approx)
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
Multiply the diameter by 3.1415 NO - ignore that! Diameter x pi (3.1416) is the circumference, the distance around a circle. Square footage is area, so the correct formula is Area = 3.1416 times radius squared. The radius would be measured in feet.

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.

To turn a 9x9 square into an octagon you can cut corners off the square. It will not be a regular octagon though.
Model each floor of the house with one or more rectangles, compute the area of each of these rectangles, and sum them to the total square footage. If the shape of you house if really complicated you may have to throw a triangle in there, but most houses can be approximated well enough using rectangles.
No, but an octagon and a square can tessellate.
You don't. Its cubinc footage, not square footage.
In order to get the square footage you need to take 13' times 15' and you will get the square footage
