What is Area of a Octagon?

Area of an octagon is defined as the region occupied inside the boundary of an octagon. In order to calculate the area of an octagon, you can divide it into small eight isosceles triangles. Calculate the area of one of the triangles and then multiply it by 8 to find the total area of the polygon.

How to Calculate Area of a Octagon?

Area of a Octagon calculator uses Area=2*(1+sqrt(2))*(Side)^2 to calculate the Area, The area is the amount of two-dimensional space taken up by an object. Area and is denoted by A symbol.

How to calculate Area of a Octagon using this online calculator? To use this online calculator for Area of a Octagon, enter Side (s) and hit the calculate button. Here is how the Area of a Octagon calculation can be explained with given input values -> 391.1026 = 2*(1+sqrt(2))*(9)^2.

FAQ

What is Area of a Octagon?
The area is the amount of two-dimensional space taken up by an object and is represented as A=2*(1+sqrt(2))*(s)^2 or Area=2*(1+sqrt(2))*(Side)^2. The side is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back.
