If the area of a square is expanded to N times of the original, the side length will be several times of the original

If the area of a square is expanded to N times of the original, the side length will be several times of the original

Let the original side length be x, and the area be x ^ 2 (the square of x). The area is enlarged by N times to nx ^ 2, and the side length is √ (nx ^ 2) = n ×√ x ^ 2 = n × X
