About Area of an Octagon Calculator
Here, we understand what an octagon is and how to find its area. Suppose we have an octagon that has 8. angles and 8. sides. All the angles and sides will be the same. Meaning the length of all the sides will be the same. We have given the drawing of an octagon in the photo below. To understand this example, look at that photo.
We have to find out the area of an octagon. How will we find out the area? The formula for the area of an octagon is A = 2a² (1 + under root of 2). Example: if we have side A of 6 meters. Here, if we take side A as 6 meters, how will we find its area? We will write this value in square meters. So, A = 2*6² (1 + 1.4142). Now, if we count, A = 2 * 36 (2.4142). Now, if we count further, A = 72 * 2.4142 we will know the area of our octagon. A = 173.82 square meters. Here, the area of our octagon is 173.82 square meters. This will be written in square meters.
How do you find the area of a octagon's ?
Now, here on this page, we will learn to calculate the area of an octagon based on the formula for calculating the area of an octagon. Let’s say you have a regular octagon with a side length of 5 units.
Apply the formula: Area = 2 * 5² (1 + √2)
Calculate the area: Area = 2 * 25 (1 + √2) ≈ 50 (1 + 1.414) ≈ 120.71 square units
So, the area of a regular octagon would be 120.71 square units.
Note: This formula only works for octagons where all sides are equal in length. If your octagon is a more wonky shape, you may need to get a little creative in measuring its perimeter.
FAQ
1. What do you understand about the differences between an octagon and a hexagon?
An octagon has eight sides while a hexagon has six sides.
2. Can I use this calculator for irregular octagons or must I only use standard octagonal shapes?
Our calculator is based on the parameters of the regular octagon where all sides of the figure are the same.
3. I get the precision to be how accurate the calculator is.
Our calculator is designed with great accuracy to provide the best results.
4. It is also applicable for the other shapes How?
No, this calculator is created ONLY for octagons.
5. Is there some algebraic expression for finding out the perimeter of the octagon?
Yes, the four-sided octagon can be calculated using the following way the perimeter of any geometrical figure is equal to the product of the side by 8.
