As shown in the figure, the side length of a square is increased by 14. The perimeter of the new square is 60 cm. How many cm is the side length of the original square?

Let the original square side length be x cm, 60 △ 4 = 15 (CM), x + 14x = 15, & nbsp; 54x = 15, & nbsp; & nbsp; X = 12; answer: the original square side length is 12 cm
