Calculate square footage, square meters, square yardage and acres for home or construction project. => from the figure, it can be seen that, side length of the octagon = b => also since the polygons are regular, therefore 2*x + b = a => from the right angled.

If the area enclosed by the square is a, and the length of each side is l, then l = √a.
In other words each grid square is one 'square centimetre'. Thus, the measure of the length of the side of a square plays a very important role. Add all sides together to find the length of each side. Just square the sides, add them, and then take the square root.
