To find the perimeter of the rectangular flower bed, we need to sum up all four sides of the rectangle.

Given that one side of the rectangular flower bed is represented by x, the other side will be (8 - x) using the constraint 0 < x < 8.

The perimeter, P, can be calculated as:

P = 2x + 2(8 - x)

P = 2x + 16 - 2x

P = 16

Therefore, the correct alternative that presents the measurement of the perimeter of this site is $\boxed{16 \, m}$.
