1) Von einem Rechteck (Länge 8cm, Breite 5cm) werden Länge und Breite um jeweils 1cm verlängert, um wie viel cm² erhöht sich der Flächeninhalt? 2) Um wie viel Prozent erhöht sich der Flächeninhalt?

Taschenrechner darf verwendet werden.

tjo na dann mal die auflösung...


mav hat´s gleich richtig mit rechenweg geschickt, seine pn an mich:

8cm * 5cm = 40cm²
9cm * 6cm = 54cm²
54cm² - 40cm² = 14cm² (Erhöhung des Flächeninhalts)

100 / 40 = 2,5 (1cm² entspricht 2,5%, 40cm² entsprechen 100%)
2,5 * 54 = 135 (54cm² entsprechen 135%)
135% - 100% = 35% (Flächeninhaltssteigerung in %)

congrats an Mav & Max

find keinen besseren ort dafür:
Glaubensbekenntnis der Mathematiker:

Ich glaube an die Mathematik, die allmächtige Wissenschaft,
Die regiert im Endlichen und im Unendlichen,
Und an Analysis, ihre eingeborene Tochter,
Empfangen durch Pythagoras,
Geboren durch Isaac Newton,
Getauft von Rieman,
Die kreuzigt und umbringt die Studenten.
Sie wird kommen zu richten die Regulären und die Singulären.
Ich glaube an das heilige Integral,
Gemeinschaft der Matrizen,
Parametrisierung der Sünden,
Und das ewige Rechnen,
Widerspruch!
