How can you find the area of a shaded region assuming the octagon is regular?

To find the area of a shaded region within a regular octagon, first calculate the area of the entire octagon using the formula ( A = 2(1 + \sqrt{2})s^2 ), where ( s ) is the length of a side. Then, determine the area of any non-shaded regions (such as triangles or smaller shapes) within the octagon and calculate their total area. Finally, subtract the area of the non-shaded regions from the total area of the octagon to find the area of the shaded region.


What is the area of octagon with the perimeter 80cm?

An octagon is a non-rigid shape. In the same way that a square can be flexed into a rhombus and reduce the area by making the rhombus thinner, an octagon can be flexed into a shape with as small an area as you like.Its maximum area is 482.8 cm2(approx).An octagon is a non-rigid shape.

How do you find the area of an octagon?

The formula for the area of a regular octagon is:A = 2 (1+ SQRT(2)) s**2 , orA = 4.8284 s**2where A= the area of the octagon, ands is the length of one side s**2 indicates s squared or s times s
