Offset command
offset the 6 unit line at a distance of 1.5 from either side of the rectangle formed
again offset the 6 unit line at a distance of 1.5 from either side
offset the 11.5 line at a distance of 3 from the bottom or top of the rectangle
offset the 6 line at a distance of 5.75 from the left or right side of the rectangle
