Answer:
The correct answer is:
Yes, the variable of interest is two-dimensional.
Explanation:
Since we know that the area of a land of five largest countries is two-dimensional.
Also , if we are using a square figure which is also two-dimensional in order to describe the area of land then it would be valid because we just used a mathematical model of equal dimension to describe these lands.
Hence, the answer is:
Yes, the variable of interest is two-dimensional.
