Aufgabe:
Familie Lumi will ein Haus bauen. Herr Lumi hat beschlossen, es alles selber zu machen. Jetzt stellt sich aber die große Frage, wie viele Ziegelsteine er denn überhaupt bestellen muss, um so ein Haus wie auf den Bildern bauen zu können! Kannst du ihm da weiterhelfen??
Lösung:
1. 3m
7m= 21m²
21m²-[(1m
2. 0,53,5m=12,25m²
3. 0,90m7m=6,30m²
6,30m²+12,25m²=18,55m² 18,55m²-4m²=14,55m² 14,55m²+18,50m²=33,05m²
4. 14,55m²
5. 3m7m=21m²
21m²-(2m²+1,5m²+4m²)= 21m²-7,5m²=13,50m² 13,50m²+14,55m²=28,05m²
6. 3,90m<math\cdot></math>12m=45,8m²
46,8m²-(3,60m²+3,75m²)= 46,8m²-7,35m²=39,45m²
7. 3,90m²3m=11,7m²
11,7m²-1,25m²=10,45m²
8. 3m
