For a square of 900 square centimeters, its side length must be 30 centimeters
In other words, as long as the length of the rectangle does not exceed 30 cm, it can be cut out
Let the width of a rectangle be x, then the length is 2x (2x ≤ 30 x ≤ 15)
x*2x=560
x^2=280
Because x ≤ 15
So, 0 ≤ x ^ 2 ≤ 225
So the equation x ^ 2 = 228 doesn't hold
So I can't cut it out
