Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. 31 mn
  2. 21 mn
  3. 35 mn
  4. 25 mn

Correct answer and explanation

Correct answer: 25 mn

Explanation: āœ… Correct Answer: D) 25 mn šŸ“š Explanation: This problem is a direct application of the Pythagorean theorem for a right-angled triangle, which states that the square of the hypotenuse (AC) equals the sum of the squares of the other two sides (AB and BC). Therefore, AC = square root of ((24 Ɨ 24) + (7 Ɨ 7)). This is the square root of (576 + 49), which equals the square root of 625. The final answer is exactly 25 mn.
