Explanation

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’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 $upper A equals left parenthesis 7 right parenthesis left parenthesis 6 right parenthesis$ , or $upper A equals 42$ . 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.
