Are monsters good at maths?

Not unless you Count Dracula.

The type of questions involving area scale factor can appear monstrous.

Honestly, they're not!

4 cm 8 cm

Area 16 cm² **What is the area of this square?**

1. Find the scale factor of the enlargement 8 ÷ 4 = Scale factor 2

**2. THIS DOES NOT MEAN THAT THE AREA IS TWICE AS BIG.**

3. Take the scale factor and square it 2² = 4

4. The area of the larger square is 4 times as big

5. 16 x 4 = 64 cm²

6 cm 18 cm

** Area = 12 cm² What is the area of this rectangle?**

1. Find the scale factor of the enlargement 18 ÷ 6 = Scale factor 3

**2. THIS DOES NOT MEAN THAT THE AREA IS THREE TIMES AS BIG.**

3. Take the scale factor and square it 3² = 9

4. The area of the larger rectangle is 9 times as big

5. 12 x 9 = 108 cm²

Scale factor 2 | Area scale factor 2² | 4 times as big |

Scale factor 3 | Area Scale factor 3² | 9 times as big |

Scale factor 4 | ||

Scale factor 5 |

Scale factor 2 | Area scale factor 2² | 4 times as big |

Scale factor 3 | Area Scale factor 3² | 9 times as big |

Scale factor 4 | Area scale factor 4² | 16 times as big |

Scale factor 5 | Area scale factor 5² | 25 times as big |

This doesn't appear so monstrous after all does it? Over to you.
