To determine the correct equation that describes the relationship between the length of one side \( l \) and the total area \( A(l) \) as given in the table, we can examine the data:

\[ \begin{align*} l & : A(l) \ 2 & : 8 \ 4 & : 16 \ 6 & : 24 \ 8 & : 32 \ \end{align*} \]

Looking for a pattern, we can see that:

  • When \( l = 2 \), \( A(2) = 8 \)
  • When \( l = 4 \), \( A(4) = 16 \)
  • When \( l = 6 \), \( A(6) = 24 \)
  • When \( l = 8 \), \( A(8) = 32 \)

We notice that \( A(l) \) is 4 times the value of \( l \) at each point:

\[ A(2) = 4 \times 2 = 8 \ A(4) = 4 \times 4 = 16 \ A(6) = 4 \times 6 = 24 \ A(8) = 4 \times 8 = 32 \]

Thus, the relationship between area and length is \( A(l) = 4l \).

So, the correct answer is:

A(l) = 4l
