\textbf{Rectangle} & \textbf{Length} & \textbf{Width} & \textbf{Perimeter} \\
\hline
A & 8 & 5 & \\
\hline
B & 18 & 4 & \\
\hline
C & 16 & 14 & \\
\hline

To fill in the perimeter for each rectangle in the given table, we need to use the formula for the perimeter of a rectangle, which is:

[tex]\[ \text{Perimeter} = 2 \times (\text{length} + \text{width}) \][/tex]

Given the following rectangles and their dimensions, we compute their perimeters step-by-step:

1. Rectangle A:
- Length: 8
- Width: 5
- Using the formula: \( 2 \times (8 + 5) = 2 \times 13 = 26 \)
- Perimeter: 26

2. Rectangle B:
- Length: 18
- Width: 4
- Using the formula: \( 2 \times (18 + 4) = 2 \times 22 = 44 \)
- Perimeter: 44

3. Rectangle C:
- Length: 16
- Width: 14
- Using the formula: \( 2 \times (16 + 14) = 2 \times 30 = 60 \)
- Perimeter: 60

4. Rectangle D:
- Length: 25
- Width: 7.4
- Using the formula: \( 2 \times (25 + 7.4) = 2 \times 32.4 = 64.8 \)
- Perimeter: 64.8

So, the filled table will look like this:

[tex]\[ \begin{tabular}{|c|c|c|c|} \hline \text{Rectangle} & \text{Length} & \text{Width} & \text{Perimeter} \\ \hline \text{Rectangle A} & 8 & 5 & 26 \\ \hline \text{Rectangle B} & 18 & 4 & 44 \\ \hline \text{Rectangle C} & 16 & 14 & 60 \\ \hline \text{Rectangle D} & 25 & 7.4 & 64.8 \\ \hline \end{tabular} \][/tex]
