What is the length of a rope required to cover the boundaries of a square with area 64 squares metres?
Correct answer: A. 32m
- A. 32m
- B. 32m2
- C. 64m
- D. 64m2
Explanation
To find the perimeter of a square with an area of 64 square meters, you first calculate the side length. The area of a square is side length squared, so for an area of 64 square meters, the side length is the square root of 64, which is 8 meters. The perimeter of a square is 4 times the side length, so it is 4 x 8 = 32 meters. Option A is correct. Options B and D are incorrect because they use square meters, which is a unit for area, not perimeter. Option C is incorrect because it confuses the area with the perimeter.
