Question

Accepted Answer

Choice A is correct. It's given that the area of a square is 64 square inches. The area A , in square inches, of a square is given by the formula A = s 2 , where s is the side length, in inches, of the square. Substituting 64 for A in this formula yields 64 = s 2 . Taking the positive square root of both sides of this equation yields 8 = s . Thus, the side length, in inches, of this square is 8 . Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect. This is the area, in square inches, of the square, not the side length, in inches, of the square. Choice D is incorrect and may result from conceptual or calculation errors.
