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.

The Math

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)•s²

where:

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