To find the fraction that represents the relationship between the area of the original square and the dilated square, we first need to calculate the areas of both squares.

  1. Area of the original square:

    • The side length of the original square = 4 units.
    • Area = side × side = \( 4 \times 4 = 16 \) square units.
  2. Area of the dilated square:

    • The side length of the dilated square = 6 units.
    • Area = side × side = \( 6 \times 6 = 36 \) square units.
  3. Form the fraction to express the relationship:

    • We want the fraction in the form (Area of the dilated square) / (Area of the original square).
    • This gives us the fraction \( \frac{36}{16} \).
  4. Simplifying the fraction:

    • \( \frac{36}{16} = \frac{9}{4} \) when simplified (by dividing both the numerator and denominator by 4).

The final result, in lowest terms, is \( \frac{9}{4} \). Since the numerator should express the area of the dilated square, the correct format of the answer would be \( \frac{36}{16} \) indicating area of dilated over area of original.

Thus, the answer is \( \frac{36}{16} \), which can also be noted as \( 9/4 \), but since the task is to express it as a fraction with 36 as the numerator, the most appropriate expression is simply \( \frac{36}{16} \).

If you were to be prompted to select from a list based on the simplifications, ensure you identify \( \frac{9}{4} \) as that is reflecting the area proportion correctly.
