I looked at his packing... he is comparing countries to a continent. In physics, that is called mixing units and your professor marks the answer wrong, regardless of whether the number is "correct."
He is comparing land masses. If he wanted he could stick a city in there for good measure, it's all about comparing things people can images with other things... No mixing of units here.
