Problem Xiaoli wanted to use a square piece of paper with an area of 400cm~2 to cut out a piece of rectangular paper with an area of 300cm~2 along the edge so that the ratio of length to width would be 3:2. Come out and start worrying. Xiao Ming saw and said, “Don’t worry about it, you can. You can certainly cut out a small piece of paper with a large piece of paper.” Do you agree with Xiaoming? Xiao Li can use this. Is a piece of paper cut to meet the requirements?
