## Categories of Parallelogram Perimeter Calculations

Category | Range | Interpretation |
---|---|---|

Small | 1-10 ft | Easy to calculate |

Medium | 10-100 ft | Requires some attention |

Large | 100+ ft | A calculator would be handy |

## Examples of Parallelogram Perimeter Calculations

Individual | Side A | Side B | Calculation | Result |
---|---|---|---|---|

Tiny Tim | 1 ft | 1 ft | 2 * (1ft + 1ft) = 4ft | 4 ft |

Medium Mary | 10 ft | 20 ft | 2 * (10ft + 20ft) = 60ft | 60 ft |

Large Larry | 100 ft | 200 ft | 2 * (100ft + 200ft) = 600ft | 600 ft |
