The perimeter of a regular octagon - the sum of the lengths of its (eight congruent) sides - is eight times the common sidelength, so the perimeter of the octagon is 
feet. One yard is equivalent to three feet, so divide this by conversion factor 3 to get 
yards - the correct response.
The perimeter of a regular octagon - the sum of the lengths of its (eight congruent) sides - is eight times the common sidelength, so the perimeter of the octagon is

The length of one side of a square is equal to the square root of its area, so, if the area of a square is 
, the common sidelength is 
. Since a square comprises four sides of equal length, the perimeter is equal to four times this length, or 
.
