In a data graphic, both the height and width of a human icon are doubled. Approximately how large will its visual area become?

Answer and explanation

Correct answer: Approximately four times

The governing mathematical concept is area scaling. If the original icon has height h and width w, its area is h×w. After doubling both dimensions, the area is (2h)×(2w)=4hw, so option A is correct. Doubling only one dimension would produce about twice the area, but doubling both dimensions produces four times the area and can exaggerate visual comparisons.
