Let the original square have sides of length L and the new square have sides of length 2L.

The resulting areas are L^2 for the original square and 4L^2 for the new square (as the length of the side is square to get the area).

The original square's area is L^2/4L^2 or 25% of the new square's area. Choice A

Say side of original square = 1

Area$$= 1^2 = 1$$

New square side is doubled = 2

Area $$= 2^2 = 4$$

Area of original square (=1) is $$\frac{1}{4}$$ times area of new square (=4)

Percentage $$= \frac{1}{4} * 100 = 25%$$
