To determine the perimeter of a regular octagon, we need to know the length of one of its sides.
In this case, each side of the regular octagon is 8 feet long.
Since an octagon has 8 sides, the perimeter [tex]\( P \)[/tex] of the octagon is calculated by multiplying the length of one side by the number of sides.
[tex]\[
P = 8 \times \text{side length}
\][/tex]
Plugging in the given side length:
[tex]\[
P = 8 \times 8 \text{ ft} = 64 \text{ ft}
\][/tex]
Thus, the perimeter of the water wheel is 64 feet.
Therefore, the correct answer is not listed in the options given. The correct perimeter should be 64 feet.
