a=apothem;
a = s/2
or
a=s/[2tan(180/4)]
Use either of the two if the measurement of the side is given.
-1
cube
If the hexagon has side length s, then the apothem is sqrt(3) * s / 2.
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
For a regular hexagon, half the side length can be calculated from the apothem via trigonometry: half_side_length = apothem x tan 30° Then: area = apothem x 1/2 x perimeter = apothem x 1/2 x side_length x 6 = apothem x half_side_length x 6 = 24 in x (24 in x tan 30°) x 6 ≈ 1995 sq in

3d structrure with equal length,height and width.
cube
They are the apothem and side length of a nonagon. So what exactly is the question?
A square is 2D (two dimensional) and is measured by length x width. A cube is 3D and measured by length x width x depth.
Area in square units = 0.5*(apothem)*(perimeter)
A cube is a 3D solid figure whose length, width and depth are of equal measurement.
If the hexagon has side length s, then the apothem is sqrt(3) * s / 2.
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.

The area of a regular octagon: A = (2 x apothem)2- (length of side)2 or in this case A= (2 x 8.45)2 - 72
