To calculate the area of a decagon, you need to know the length of one side. The decagon is a ten-sided polygon, and its area can be calculated using a specific formula.
Decagon Area Calculation Formula
The area (A) of a regular decagon can be calculated using the formula:
A = (5 * s^2) / (2 * tan(π / 10))
Where:
- A is the area of the decagon.
- s is the length of one side of the decagon.
To use this formula, simply input the length of one side into the calculator above, and it will compute the area for you.
Understanding Decagons
A decagon is a polygon with ten sides and ten angles. Regular decagons have equal side lengths and equal angles, making them symmetrical. The internal angles of a regular decagon measure 144 degrees each, and the sum of all internal angles is 1440 degrees.
Applications of Decagons
Decagons can be found in various fields, including architecture, design, and art. They are often used in tiling patterns, decorative elements, and even in some types of games. Understanding how to calculate the area of a decagon can be useful for designers and architects when planning spaces and layouts.
Example Calculation
For instance, if the length of one side of a decagon is 5 units, you can calculate the area as follows:
Using the formula:
A = (5 * 5^2) / (2 * tan(π / 10))
After performing the calculations, you would find that the area is approximately 71.96 square units.
