Correct Answer: A

Rationale

Choice A is correct. The area $A$ , in square meters, of a rectangle is the product of its length $l$ , in meters, and its width $w$ , in meters; thus, $A = l w$ . It's given that a rectangle has an area of $63$ square meters and a length of $9$ meters. Substituting $63$ for $A$ and $9$ for $l$ in the equation $A = l w$ yields $63 equals 9 w$ . Dividing both sides of this equation by $9$ yields $7 equals w$ . Therefore, the width, in meters, of the rectangle is $7$ .

Choice B is incorrect. This is the difference between the area, in square meters, and the length, in meters, of the rectangle, not the width, in meters, of the rectangle.

Choice C is incorrect. This is the square of the length, in meters, not the width, in meters, of the rectangle.

Choice D is incorrect. This is the product of the area, in square meters, and the length, in meters, of the rectangle, not the width, in meters, of the rectangle.
