Question

What is the area, in square inches, of a rectangle with a length of 7 inches and a width of 6 inches?

Accepted Answer

Choice C is correct. The area, A , of a rectangle is given by the formula A = l w , where l represents the length of the rectangle and w represents its width. It&rsquo;s given that the rectangle has a length of 7 inches and a width of 6 inches. Substituting 7 for l and 6 for w in the formula A = l w yields A = 7 6 , or A = 42 . Thus, the area, in square inches, of the rectangle is 42 . Choice A is incorrect. This is the sum, not the product, of the length and width of the rectangle. Choice B is incorrect and may result from conceptual or calculation errors. Choice D is incorrect. This is twice the area, in square inches, of the rectangle.
