Have you ever come across a regular octagon and wondered how to find its area? Well, you’re in the right place! In this article, we will walk you through the steps to calculate the area of a regular octagon. So, let’s dive in!

What is a Regular Octagon?

Before we begin, let’s quickly understand what a regular octagon is. A regular octagon is a polygon with eight equal sides and angles. In simple words, all sides of a regular octagon have equal length, and all interior angles are the same.

Formula to Calculate the Area of a Regular Octagon

To calculate the area of a regular octagon, you can use the following formula:

A = 2 * S^2 * (1 + √2)

Where:

  • A represents the area of the regular octagon
  • S denotes the length of any side of the regular octagon

Step-by-Step Calculation

Now let’s break down the formula into simple steps to calculate the area of a regular octagon:

  1. Measure the length of any side of the regular octagon and note it down.
  2. Square the value obtained in Step 1. (S^2)
  3. Multiply the result from Step 2 by 2.
  4. Calculate the value of (1 + √2).
  5. Multiply the value obtained in Step 3 by the value from Step 4.

Example Calculation

Let’s say the length of one side of a regular octagon is 8 units. Now, let’s calculate its area using the steps mentioned above:

  1. Length of one side (S) = 8 units.
  2. 8^2 = 64.
  3. 2 * 64 = 128.
  4. (1 + √2) = 2.414.
  5. 128 * 2.414 = 309.632 square units.

Therefore, the area of the regular octagon with a side length of 8 units is 309.632 square units.

Wrapping Up

Congratulations! You’ve successfully learned how to calculate the area of a regular octagon. Remember, a regular octagon is a polygon with eight equal sides and angles, and the area can be found using the formula: A = 2 * S^2 * (1 + √2). By following the step-by-step calculation process, you can easily find the area of any regular octagon.
