Final answer:
The side length of the scaled copy of the square can be determined by multiplying the side length of the original square by the scale factor. In this case, the side length could be 8 units.
Step-by-step explanation:
The side length of the scaled copy of the square can be determined by multiplying the side length of the original square by the scale factor. Since the scale factor is greater than 1, the side length of the scaled copy will be greater than the side length of the original square. In this case, we can determine the side length of the scaled copy by multiplying the side length of the original square by 2 (twice the original length). Therefore, the side length of the scaled copy could be 8 units.
