For problems involving regular octagons 45 45 90 triangles can come in handy.

Formula for area of regular octagon. Area of octagon calculator. Since there are as many of these triangles as the polygon has sides eight for an octagon you have to multiply the area of this triangle by the number of sides. But first here are two great tips for this and other problems.

Area of octagon 8 base height 2 perimeter apothem 2. Sides of the regular octagon are always congruent. We know that the area of a regular octagon side2 2 2 2 502 2 2 1 414 2500 2 2 828 2500 4 828 12070 cm 2.

Now the formula for computing the area of a regular octagon can be given as. A regular octagon is a closed figure with sides of the same length and internal angles of the same size. Enter one value and choose the number of decimal places.

In order to calculate the area of an octagon we divide it into small eight isosceles triangles. Note that the base of the triangle is the length of a side of the octagon. Formula for area of an octagon.

Find the area of a regular octagon whose side is 50 cm. Given that side s 50 cm. Area of an octagon 2a 2 1 sqrt 2 where a is the length of any one side of the octagon.

Area of an octagon formula octagon is a polygon with eight sides when all these sides are equal it becomes a regular octagon. Calculations at a regular octagon a polygon with 8 vertices. The smallest polygon in mathematics is triangle.

This form is familiar from being used as stop sign. You will obtain the total area of the octagon. So the above demonstration described several methods to calculate the area of an octagon.

A regular polygon has equal length on all sides and equal internal and external angles of about 135 degrees and 45 degrees respectively. It is a two dimensional figure connected using straight lines. It has eight lines of reflective symmetry and rotational symmetry of order 8.

Area of an octagon is defined as the region occupied inside the boundary of an octagon. A regular octagon is represented by the schläfli symbol 8.
