A pentagon is a polygon with 5 sides or 5 angles. There are 2 types of pentagons: regular pentagon (all sides and angles are equal) and irregular pentagon (sides and angles are not equal).
The area of a regular pentagon equals side length a, for an irregular pentagon side length varies.
Calculating the area of a pentagon can be quite complex, relatively harder to remember compared to other shapes like squares, rectangles, diamonds... Therefore, finding the easiest way to remember or having your own tricks is essential.
HOW TO CALCULATE THE AREA OF A PENTAGON
To calculate the area of a regular pentagon, you need to know the length of its 5 sides. Then, apply the formula mentioned above to get the final result.
+ Calculating the area of an irregular pentagon:
If the problem requires calculating the area of a pentagon but not a regular one, you can follow these steps:
- Connect 2 out of the 5 vertices of the pentagon to form 2 shapes: a triangle and a quadrilateral.
- Calculate the area of the triangle and the quadrilateral based on the given data in the problem, then add the 2 results together to get the area of the pentagon.

A pentagon may remind you of certain names like a Pentagon or a 5-pointed star, a sea star... In reality, the formula for calculating the area of a pentagon is also commonly used to calculate the area of objects, solid shapes.
Here's our guide to help you calculate the area of regular or irregular pentagons. In case you need to solve geometric problems or calculate the area of a specific plane, feel free to apply the formula above.
