When the side of a square increases by 0.5%, the new side length is 100% + 0.5% = 100.5% of the original side length.
Therefore, the new area of the square is (100.5%)^2 = 1.01 times the original area.
To find the percentage increase in area, we calculate:
(1.01 - 1) / 1 * 100% = 1%
Therefore, the approximate percentage increase in area is 1%.
