Explanation

Choice C is correct. The perimeter of a quadrilateral is the sum of the lengths of its four sides. It's given that the rectangle has a length of $13$ and a width of $6$ . It follows that the rectangle has two sides with length $13$ and two sides with length $6$ . Therefore, the perimeter of the rectangle is $13 + 13 + 6 + 6$ , or $38$ .

Choice A is incorrect. This is the sum of the lengths of the two sides with length $6$ , not the sum of the lengths of all four sides of the rectangle.

Choice B is incorrect. This is the sum of the lengths of the two sides with length $13$ , not the sum of the lengths of all four sides of the rectangle.

Choice D is incorrect. This is the perimeter of a rectangle that has four sides with length $13$ , not two sides with length $13$ and two sides with length $6$ .
