Area of a Dodecagon Formula: Area of 12-gon is based on the side length (S). It can be calculated by multiplying the products of 3 and squared side value with the sum of 2 and √3.

Formula:

dodecagon
Area = 3 × S2 × (2 + √3) Where, s = Side Length

Dodecagon: It is a twelve-sided polygon and is also called as 12-gon. All the sides and interior angles are of equal length with the measurement equal to 150 degrees and the measurement of the center angle is equal to 360 degrees.

Use this online area of a dodecagon calculator to simplify your 12-gon area calculation work. All the results given by this tool are highly reliable and accurate.

Example:

Calculate area of a dodecagon with side length of 8 cm.

Solution:

Dodecagon Area = 3 ×82 × (2 + √3)
= 716.5538 cm2
