Respuesta :

the answer is D
Both sides get enlarged 2 by 4 and 3 by 3

Answer: C.7 inches × 10.5 inches

Step-by-step explanation: Aspect ratio is maintained in an optical magnification.

Aspect ratio is the ratio between the length and the breadth of an image.

A photocopier uses light and lens combination to magnify an image optically in which the aspect ratio is conserved.

The given image has the dimensions  2 inch by 3 inch, so its aspect ratio is 2:3.

Now from the given options we check for the same ratio and arrive at 7:10.5 .

As,

[tex]\frac{7}{10.5} = \frac{7\times 10}{10.5\times 10} = \frac{70}{105} = \frac{14}{21} = \frac{2}{3}[/tex]
