**Topic :** Perimeter and Area |

**Equipment Needed : **Poster Paper |

**Victorian Curriculum outcome : **Calculate the perimeter and area of rectangles using familiar metric units |

**Task description : **Students design eight different rectangular blocks of land and calculate the perimeter and area of each. If they are using a scale drawing, 1cm should be equivalent to 1m. Students calculate the cost for each block of land based on area ($100/m^{2}) and perimeter (the blocks of land need to be fenced, at a cost of $200/m). |

**Assessment options : **Scale drawing on poster paper or cardboard; Google SketchUp model. |

**Teacher notes : **Ensure students using Google SketchUp are using it correctly and do not waste time adding unnecessary detail to their models. For scale drawings, the scale of 1cm = 1m means fairly small blocks of land, but it avoids further confusion with converting scale. |
