<em>Answer:</em>
<em>The expression which is does not correct is A. 9 + 12</em>
<em>Step-by-step explanation:</em>
<em>Length of the rectangular garden = 12 feet</em>
<em>Width of the rectangular garden = 9 feet</em>
<em>We need to find the perimeter of the garden.</em>
<em>The perimeter of the garden is given by the formula = 2 × (Length + Width)</em>
<em>⇒ Perimeter = 2 × (12 + 9)</em>
<em> = 2 × 12 + 2 × 9</em>
<em> = 12 + 12 + 9 + 9</em>
<em>So, All the options B. , C, and D. are correct to find the perimeter of the rectangular field.</em>
<em>Therefore, The expression which is does not correct is A. 9 + 12</em>

Answer:
Center of dilation → (0, 0)
Step-by-step explanation:
Vertices of a triangle ABC are A(3, 6), B(7, 6) and C(7, 3).
If this triangle is dilated by a scale factor of 'k' about the origin,
Rule for the dilation is,
(x, y) → (kx, ky)
If vertex A is dilated by a scale factor of 3 about the origin,
A(3, 6) → A'(3×3, 3×6)
→ A'(9, 18)
Therefore, center of dilation is origin (0, 0).
