Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.
The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w).
In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:
P = 2(l + w) = 2 x 12 = 24 ft.
Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:
[tex]n = \frac{24}{\frac{2}{3}} = 36[/tex]
