I found some ROI indicators and I want to know how the calculation is made.

Please note that these calculations are indicative only and may in no way represent a true ROI.

• The saved floor area: It is the area of a hypothetical room without windows or doors. It is calculated with all boards end-to-end: It is the sum of the widths of the boards, divided by 4 the whole squared. (width of the room / 4)²
• The saved paper area: The area occupied on the wall, i.e. the total width of the room multiplied by the height.
