The expression which is does not correct is A. 9 + 12

Step-by-step explanation:

Length of the rectangular garden = 12 feet

Width of the rectangular garden = 9 feet

We need to find the perimeter of the garden.

The perimeter of the garden is given by the formula = 2 * (Length + Width)

⇒ Perimeter = 2 * (12 + 9)

= 2 * 12 + 2 * 9

= 12 + 12 + 9 + 9

So, All the options B., C, and D. are correct to find the perimeter of the rectangular field.

Therefore, The expression which is does not correct is A. 9 + 12
