Final answer:
The gate width is 2m.
Step-by-step explanation:
The gate width is not provided in the question, but we can calculate it using the given information. The gate is 2m into the paper, which means it extends into the page by 2m. Since the gate is most likely a straight line, the gate width would be the same as the length of the line in the direction perpendicular to the paper, which is the height of the line.
Therefore, the gate width is 2m.
