Formula:

For a regular octagon, the area can be precisely calculated using the length of one of its sides (s) with the following formula:

Area = 2 × (1 + √2) × s2

  • s: Represents the length of a single side of the regular octagon.
  • √2: The mathematical constant for the square root of 2, approximately 1.41421356.

This formula is derived from dividing the octagon into eight congruent isosceles triangles and summing their areas, incorporating the square root of 2 for its geometric properties.
