Let's solve the mathematical expression:

- We need to find \( ? \) in the equation: \( 45\% \times 1600 + ?^2 = 1044 \).

- Calculate \( 45\% \) of 1600:

- \( 45\% = 0.45 \)

- \( 0.45 \times 1600 = 720 \)

- Substitute back into the equation:

- \( 720 + ?^2 = 1044 \)

- Solve for \( ?^2 \):

- \( ?^2 = 1044 - 720 \)

- \( ?^2 = 324 \)

- Find the square root of 324:

- \( ? = \sqrt{324} = 18 \)

- Correct Answer: Option 1 - 18
