none of the choices has a perimeter of 188 ft. All have a perimeter of 376 ft.
A square has maximum area for a given perimeter, so the garden should be 47 by 47, with area = 2209.
Assuming one of the given choices, you'd want a square, so go with 94x94. Heck, the table shows it has the largest area.
