Octagon formula side length. The octagon layout calculator is a handy carpenter's tool for laying out a perfect octagon. The calculator tool is loading. The perpendicular distance from the center of a polygon to one of its sides is the apothem.

The side length is 2/[cos(pi/4)*cos(pi/8)] = 3.06 inches, approx. Area of a regular octagon: If you know the length of one of the sides of the octagon, you can calculate its perimeter using the following formula:

Seeing as it's tolerance is to the nearest 1/16, it's no good for small projects such as jewlery boxes. Just enter one side and the rest of them will be calculated so you have the whole layout. An octagon is a polygon with eight sides;

It's written in html and javascript. For example, here’s how you’d find the area of eightplu in the figure below given that it’s a regular octagon with sides of length 6. My equation is as follows, (a/√2)*2+a=b, or a over radical 2, times 2, plus a, equals b.

As we know that perimeter is simply the sum of all eight sides. Octagon formulas to calculate area, perimeter & side Suppose that each side has length s.

Ri= a / 2 * ( 1 + √2 ) angle: Therefore, if you already know the area, you can derive the side length using the following formula, where sqrt L = s + 2 a.
