A square, cut 6cm on one side, cut 2cm on the other side, the remaining rectangle is 68cm2 less than the original square area?
Let the side length of a square be xcm. According to the meaning of the question, we can get: (X-6) (X-2) = x2-68. After sorting out, we can get: - 8x = - 80, and the solution is: x = 10. Answer: the side length of a square is 10cm
