# Area of Parallelograms

We know four kinds of **parallelograms**. They are a square, a rectangle, a rhombus and a rhomboid. They have different formulas of their areas.

To count the area of a rhombus and of a rhomboid we need to know the length of its edge and its height. So formulas for a rhombus and a rhomboid are same.

Topic Name | Formula |
---|---|

Area of Square | A = a × a |

Area of Rectangle | A = a × b |

Area of Rhombus | A = a × h |

Area of Rhomboid | A = a × h |
