What is the perimeter of a rectangle with length 9 and width 4?

Explanation:
The perimeter of a rectangle is found by adding all four sides, which is the same as twice the sum of its length and width. With length 9 and width 4, the sum is 9 + 4 = 13. Doubling that gives 26, so the perimeter is 26. This matches the correct value. The other numbers don’t fit because they would require a different total for length plus width (for example, 22 would come from doubling 11, 28 from doubling 14, etc.).
