Arisa [49]

Answer:

Option D

Step-by-step explanation:

Formula to be used,

Scale factor = $\frac{\text{Dimension of the image rectangle}}{\text{Dimension of the original}}$

By this formula,

$\frac{7}{2}=\frac{\text{Length of the dilated rectangle}}{\text{Length of the original rectangle}}$

$\frac{7}{2}=\frac{L}{22}$

L = $\frac{7\times 22}{2}$

= 77 inches

Similarly, width of the the dilated rectangle = $\frac{7}{2}\times 10$

= 35 inches

Perimeter of the new rectangle = 2(Length + width)

= 2(77 + 35)

= 224 inches

Option (D) will be the correct option.
