## The Formula

The area of a star shape can be calculated using the formula:

```
Area = 0.4 * n * s^2 / tan(π/n)
```

Where `n`

is the number of points and `s`

is the length of a side.

## Star Shape Categories

Category | Points | Side Length (Inches) | Area (Square Inches) |
---|---|---|---|

Small Star | 5 | 1 | 1.7204 |

Medium Star | 5 | 2 | 6.8819 |

Large Star | 5 | 3 | 15.484 |

## Examples

Individual | Star Type | Calculation |
---|---|---|

Little Timmy | Small Star | 0.4 * 5 * 1^2 / tan(π/5) = 1.7204 |

Average Joe | Medium Star | 0.4 * 5 * 2^2 / tan(π/5) = 6.8819 |

Big Bertha | Large Star | 0.4 * 5 * 3^2 / tan(π/5) = 15.484 |

## Calculation Methods
