If a shape is dilated by a scale factor of 3, what is the resulting perimeter? A.)The new perimeter is 9 times larger than the preimageB.)The same as theperimeter of thepreimageC.)The new perimeter is 4 times the originalD.)The new perimeteris 3 times largerthan the preimage

Respuesta :

The perimeter of the figure is sum of the side of the figure. If figure is dilated by factor of 3, means that each side of the figure is dilated by 3.

The addition of dilated side to obtain the perimeter results in 3 times the original perimeter.

So new perimeter is 3 times larger than the preimage. Option D is correct.
