The area of a square is increased by four times, and its side length becomes the same______ When the area is expanded to nine times the original, its side length becomes the original______ When the area is expanded to 100 times the original, its side length becomes the original______ When the area is n times the original, its side length becomes the original______ Times

The area of a square is increased by four times, and its side length becomes the same______ When the area is expanded to nine times the original, its side length becomes the original______ When the area is expanded to 100 times the original, its side length becomes the original______ When the area is n times the original, its side length becomes the original______ Times

If the area of a square is increased by 4 times, its side length becomes 4 = 2 times; if the area is increased by 9 times, its side length becomes 9 = 3 times; if the area is increased by 100 times, its side length becomes 100 = 10 times; if the area is increased by n times, its side length becomes n times
