Enter a value for all fields

The **Area of a Heptagon** calculator computes the area of a regular heptagon, a polygon with 7 equal sides of length (**s**). * Regular Heptagon*

**INSTRUCTIONS:**Choose your length units (e.g. feet or meters) and then enter the following:

**s**- the length of the sides of the heptagon.

**Heptagon Area**: The area is returned in square meters, but can be automatically converted to other units such as square feet or acres via the pull-down menu.

A regular heptagon has seven equal sides and equal angles. The formula for the area of a heptagon is:

**A = ^{7}/_{4}•cot(^{π}/_{7})•s^{2}**

where:

- A is the area of the regular heptagon
- s is the length of a side.

- Area of a Circle - Multiple functions to compute the area of a circle or portions of a circle.
- Area of Triangle - Three Sides
- Area of Quadrilateral - Four Sides
- Area of Pentagon - Five Sides
- Area of Hexagon - Six Sides
- Area of Heptagon - Seven Sides
- Area of Octagon - Eight Sides
- Area of Nonagon - Nine Sides
- Area of Decagon - Ten Sides
- Area of Hendecagon - Eleven Sides
- Area of Dodecagon - Twelve Sides
- Area of Polygon - Any number of sides (n).
