After the side length of a square increases by 2 / 5, its area increases by 96 square centimeters. What is the area of the original square? Is there no arithmetic solution

After the side length of a square increases by 2 / 5, its area increases by 96 square centimeters. What is the area of the original square? Is there no arithmetic solution

Suppose that the original square's side length is a, and the original square's area is: S1 = a square. After the side length increases by 2 / 5, it becomes: a (1 + 2 / 5) = 7a / 5. After the side length increases, the total area is: S2 = (7A / 5) x (7a / 5) = a square x49 / 25
