To determine the correct equation that describes the relationship between side length \( l \) and area \( A(l) \) from the given table, we can analyze the values:
- For \( l = 2 \), \( A(2) = 8 \)
- For \( l = 4 \), \( A(4) = 16 \)
- For \( l = 6 \), \( A(6) = 24 \)
- For \( l = 8 \), \( A(8) = 32 \)
Observing the pattern, we can see that:
- \( A(2) = 4 \times 2 = 8 \)
- \( A(4) = 4 \times 4 = 16 \)
- \( A(6) = 4 \times 6 = 24 \)
- \( A(8) = 4 \times 8 = 32 \)
From this, we can derive that the area \( A(l) \) is equal to \( 4 \) times the length \( l \). Therefore, the correct equation that describes the relationship is:
\[ A(l) = 4l \]
So, the answer is:
A(l) = 4l (upper A left parenthesis l right parenthesis equals 4 l)
