Let x = length of one side of the square photograph. Since you are looking for the perimeter, you are looking for the distance around the square; and since all of the sides of a square are of equal length, you have:
Perimeter = x + x + x + x = 4x.
The area of any rectangle is length * width. In your case, since the length and width are equal, . We know from the problem that Area = 300, so we have:

(Taking the square root of both sides)
(simplifying the expression)
The perimeter = = = = 69.28
Therefore the perimeter of the square photograph is 69.28 inches.
