There is no useful or suitable method shown on the list below.
A regular octagon is formed from 8 isosceles triangles, each having a base length of 'd' (the length of a side of the octagon) and base angles of 67.5°. The height of one triangle is, 1/2d.tan67.5 The area of one triangle is, 1/2(base x height) = 1/2d.1/2d.tan67.5 = 1/4.d2tan67.5 The area of the octagon = 8 x area of one triangle = 2d2tan 67.5 = 4.8284d2. Thus, 4.8284d2 = 43560 : d2 = 9021.5714 : d = 94.982 The perimeter = 8d = 759.86 ft. (2dp). Note : It can be shown that the area, A = d2(2 + 2√2).

A triangle has 3 line segments
No, it could not. A triangle cannot have a perimeter of length zero.
Is it an invisible ellipse ... I can't see it

The smallest unit of length shown is millimeters. There are 1000 millimeters in one meter.
Shown is an irregular verb because shown is different to ending in -ed. Does shown end in -ed? No it doesn't end in -ed so which makes it an irregular verb.
