Question

A rectangle has an area of 63 square meters and a length of 9 meters. What is the width, in meters, of the rectangle?

Accepted Answer

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 = 9 w . Dividing both sides of this equation by 9 yields 7 = 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.
