It is not possible to hold both of those given dimensions.
If the side length is 6 m, then the apothem is about 7.42 m.
If the apothem is 3.8 m, then the side length is about 3.15 m.
If the side length is 6 m, then the apothem is about 7.42 m.
If the apothem is 3.8 m, then the side length is about 3.15 m.

The area of the regular octagon:
8(3*3.8) = 8*11.4 = 91.2 m^2
or
7.6^2 - 2*0.8^2 = 56.48 m^2
or
(7.6*6 + (3√3 * 6^2)/2 = 139.131... m^2
or
(7.6*6 + 6*0.8*4 + 4*0.8^2) = 67.36 m^2
8(3*3.8) = 8*11.4 = 91.2 m^2
or
7.6^2 - 2*0.8^2 = 56.48 m^2
or
(7.6*6 + (3√3 * 6^2)/2 = 139.131... m^2
or
(7.6*6 + 6*0.8*4 + 4*0.8^2) = 67.36 m^2

Given s = 6
A = 2[1 + √(2)]s^2
A = 2[1 + √(2)]6^2
A = 173.82 m^2 answer//
A = 2[1 + √(2)]s^2
A = 2[1 + √(2)]6^2
A = 173.82 m^2 answer//
