Find the area of an octagon with a radius of 6 meters

A regular octagon has all its eight sides congruent. The line segments joining each of the vertices of a regular octagon to its center are called the radii of the octagon. These 8 radii divide a regular octagon into 8 congruent isosceles triangles. Area of each isosceles triangle is

,

where a is length of the side of the octagon and is the angle between two radii of the octagon.

In regular octagon

.

Then the area of regular octagon is
