## Decagon Calculation Formula

The area of a decagon can be calculated using the formula:

```
Area = 2.5 * side_length^2 * sqrt(5 + 2*sqrt(5))
```

## Decagon Calculations and Results Interpretation

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

0-10 sq. ft. | Small Decagon |

10-50 sq. ft. | Medium Decagon |

50+ sq. ft. | Large Decagon |

## Example Calculations

Individual’s Name | Side Length (ft) | Calculated Area (sq. ft) | Calculation Method |
---|---|---|---|

Johnny Appleseed | 2 | 17.36 | Johnny threw an apple, and it landed 2ft away. He then used the formula above. |

## Calculation Methods

Method | Advantages | Disadvantages | Accuracy |
---|---|---|---|

Using the formula | Accurate and fast | Requires math knowledge | High |

## Evolution of Decagon Calculation

Time Period | Calculation Method |
---|---|

Ancient Greece | Guessing |

17th Century | Using a compass and straightedge |

Now | Using the formula |

## Limitations of Decagon Calculation

**Measurement Error**: The side length of the decagon must be measured accurately.**Rounding Error**: The accuracy of the result can be affected by rounding errors.

## Alternative Methods

Method | Pros | Cons |
---|---|---|

Using a computer program | Fast and accurate | Requires a computer or smartphone |
