Explanation

Choice D is correct. The area $A$ , in square centimeters, of a rectangle can be found using the formula $A = l w$ , where $l$ is the length, in centimeters, of the rectangle and $w$ is its width, in centimeters. It's given that the rectangle has a length of $36$ centimeters and a width of $34$ centimeters. Substituting $36$ for $l$ and $34$ for $w$ in the formula $A = l w$ yields $upper A equals 36 left parenthesis 34 right parenthesis$ , or $upper A equals 1,224$ . Therefore, the area, in square centimeters, of this rectangle is $1,224$ .

Choice A is incorrect and may result from conceptual or calculation errors.

Choice B is incorrect. This is the perimeter, in centimeters, not the area, in square centimeters, of the rectangle.

Choice C is incorrect and may result from conceptual or calculation errors.
