Logo Programming Source to Draw a Box

You can visualize a Box by using this:

to box :a :b :c :d
   pu setxy :a :b pd
   repeat 2 [fd :d-:b rt 90 fd :c-:a rt 90]
end

The idea is to move to a lower left corner and draw a rectangle by moving the turtle. You can compute the steps from two coordinates
