Combine dimensioned shapes and rooms, subtract explicit exclusions and estimate waste-adjusted coverage and whole material packages.

02 / RESULT & INTERACTIVE INSPECTION
Each outlined shape is an independent dimensioned schematic, not a surveyed floor plan or a claim about relative room placement. Exclusions are shown separately, not positioned inside an unmeasured room. Base-height triangles use an area-equivalent right-triangle schematic.
Area 1: total 11.14836 m² across 1 identical instance(s). This area is included.
| Area | Shape | Quantity | Operation | Area m² |
|---|---|---|---|---|
| Area 1 | rectangle | 1 | Add | 11.1484 |

Each included shape’s area is multiplied by its quantity, then included areas are summed. Exclusion rows and an optional additional numeric cutout are subtracted once to obtain usable area.

Rectangle, square, base-height triangle, circle by radius and trapezoid by parallel bases/perpendicular height. Multiple-room mode permits independent mixtures rather than assuming one rectangular building footprint.
Choose feet:inches and enter values such as 10:6 for ten feet six inches, with the inch component below twelve. Both dimensions convert before area calculations; plain decimal feet and metric units are also available.
No. They are independent dimensioned area schematics, with no inferred adjacency, overlap or exclusion placement. Base-height triangles use an area-equivalent schematic, not a uniquely surveyed apex.
Waste-adjusted material area equals usable area times one plus the entered waste percentage. Divide by supplier coverage and round up to whole packages. Optional cost is whole packages times entered package price.
One foot is 0.3048 m, so one square foot is 0.09290304 m². One square yard is nine square feet or 0.83612736 m². Exclusions cannot exceed included area.
