Answer 1

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

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
