Correct answer: A. 180

  • A. 180
  • B. 120
  • C. 170
  • D. 200

Explanation

The correct answer is 180. By multiplying the length of one side (45) by the total number of sides (4), you get the perimeter of the square as 45 × 4 = 180. Option A is correct because it follows the correct calculation method. Options B, C, and D are incorrect as they deviate from the proper approach to determining the perimeter of the square.
