First-case tutorial
What you actually do
- Treat the briefing as context only. Every elimination must still be proven by a formal record.
- Multiply length by width.
- Compare with certified area.
- Select the only mismatch.
Formal rules
- All rooms are rectangular for this schedule.
- Measurements are internal finished dimensions.
Cases in this family rotate through multiple reasoning archetypes, so higher difficulty changes the deduction structure rather than simply adding more rows.
