Explanation

Choice C is correct. The area of a rectangle with length $l$ and width $w$ can be found using the formula $A = l w$ . It’s given that the rectangle has a length of $17 cm$ and a width of $7 cm$ . Therefore, the area of this rectangle is $upper A equals 17 left parenthesis 7 right parenthesis$ , or $119 cm squared$ .

Choice A is incorrect. This is the sum of the length and width of the rectangle, not the area.

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

Choice D is incorrect. This is the sum of the length and width of the rectangle squared, not the area.
