What is a Polygon?
A polygon is a simple shape made up of straight lines that connect to form a closed figure. The lines of a polygon are called sides and where the sides meet is called vertices (plural of vertex).Polygons include triangles, rectangles, and pentagons, among others.
For example, a triangle is a polygon with three sides and three vertices, while a square is a polygon with four sides and four vertices. Polygons are commonly found in geometric shapes, maps and designs, and they come in various sizes and configurations.
What is Meant by the Area of a Regular Polygon?
In geometry, a polygon is a plane shape with straight sides. A polygon must have at least three sides. There are various types of polygons, including regular, irregular, convex, concave, and more. Regular polygons have equal sides and equal angles inside. They are closed shapes with at least three sides, where each side is the same length and all angles are equal.

Frequently Asked Questions
What does this tool do?
Works out the area (and perimeter, depending on the mode) of a regular polygon — any shape where all sides and angles are equal, from a triangle up to whatever number of sides you enter.
What's the "Area by (using length)" dropdown for?
Lets you pick which method to calculate by. "Using length" means you're calculating area based on the side length and number of sides — other modes in that dropdown likely let you calculate using different known values, like the apothem or perimeter instead.
How do I use it?
Pick your calculation method, enter the side length and number of sides, and the surface area shows up in the Output box.
Does it work for any polygon, or just specific shapes?
Any regular polygon — triangle, square, pentagon, hexagon, and beyond, as long as you know the number of sides.
What counts as "number of sides"?
However many sides the shape has — 3 for a triangle, 6 for a hexagon, 8 for an octagon, and so on.
Who actually needs this?
Students working through geometry problems, and anyone in design or construction dealing with polygon-shaped spaces or materials who needs the area without working out the formula by hand.
