Explanation:

Let's solve the given equation step by step:

- Calculate each multiplication separately:

- $72\times 35=2520$

- $145\times 58=8410$

- $65\times 19=1235$

- Sum these results:

- $2520+8410+1235=12165$

- Calculate the square root and add to the sum:

- $\sqrt{324}=18$

- $12165+18=12183$

- Correct answer is the what 12183 equals with:

- Option 5 ("None of these") is incorrect because 12183 is not listed.

- Comparing $12183$ with options:

- Options 1 (12515), 2 (12616), 3 (12826), and 4 (12813) don't match.

- Thus, Correct answer is: - None of these (Option 5)
