Calculating The Area Of A Regular Dodecagon
Welcome to our article on calculating the area of a regular dodecagon! In this tutorial, we will guide you through the steps of finding the area of this twelve-sided polygon. Whether you're a student learning geometry or just curious about the math behind this shape, this article is for you. So, let's dive in!
What is a Regular Dodecagon?
A regular dodecagon is a polygon with twelve equal sides and twelve equal angles. Each angle measures 150 degrees, and the sum of all the angles is 1800 degrees. The regular dodecagon can be inscribed in a circle, where each vertex touches the circle, and the sides are tangent to the circle.
Formula for Calculating the Area of a Regular Dodecagon
The formula for finding the area of a regular dodecagon is as follows:
Area = (3 × √3 × s2)/2
Where s is the length of one side of the dodecagon.
Step-by-Step Guide to Calculating the Area of a Regular Dodecagon
Now that we have the formula, let's break it down into steps:
- Measure one side of the dodecagon (s).
- Square the length of one side (s2).
- Multiply the squared length by 3 (√3 × s2).
- Divide the result by 2 ((3 × √3 × s2)/2).
Example Calculation
Let's say we have a regular dodecagon with a side length of 5 cm. To find the area, we use the formula:
Area = (3 × √3 × s2)/2
Area = (3 × √3 × 52)/2
Area = (3 × √3 × 25)/2
Area = 32.48 cm2
