Berechne die Fläche der Rechtecke.
  • Zeichne die Rechtecke mit Lineal auf ein kariertes Blatt.
  • Berechne den Flächeninhalt. Achte dabei auf eine korrekte Schreibweise (4-Schritt-Löseverfahren)!
  • Du musst nicht alle Aufgaben rechnen, wenn du dir sicher bist, dass du den Flächeninhalt sicher berechnen kannst!
