A one-meter door only means that the wall should be at least one meter. But I don't know if he wants to give up the fence by one meter, or if he wants to enclose it and then cut it down.

Take one meter as an example: (1) Rectangular length: 32-2x.

(2) According to the meaning of the question, there is x(32-2x)= 130.

32x-2x^2- 130=0，

x^2- 16x+65=0，

Discriminant△ = (-16) 2-4 *1* 65 =-4.

Therefore, it is impossible to enclose a 130㎡ flower garden under the condition of satisfying the meaning of the question.

(3) The largest garden area is required. Let the garden area be y, and there is a function.
