I assume that you mean to simultaneously create a set of four walls touching on their ends, arranged in a rectangle.
Tracker not necessary for this operation.
-set working units to feet.
-activate wall tool.
-select rectangle drawing option.
-click with mouse to locate lower left corner of rectangle. (start position)
-enter "x22y18" or "x18y22" (you didn't specify the proportion of your rectangle)
-enter "return."
It should draw a rectangle.
