To find the perimeter of a rectangle, you can use the formula:

\[ P = 2 \times (length + width) \]

In this case, the length of the rectangle is 8 and the width is 3. Plugging these values into the formula gives:

\[ P = 2 \times (8 + 3) \]

\[ P = 2 \times 11 \]

\[ P = 22 \]

This calculation shows that the perimeter of the rectangle is indeed 22. Thus, the correct answer reflects the accurate application of the perimeter formula for rectangles, ensuring that both the length and width are appropriately included.
