NEED HELP NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.2. What should he do to the dimensions in order to have a similar rectangle that's area is only 2 in.2?

Divide them by nine.
Divide them by six.
Divide them by three.
multiply them by three.

Answer 1

Divide them by three

Answer 2

Area of Original rectangle = 18 in²→→Pre image

Area of Rectangle after Dilation =2 in²→→Image

As, Pre image and image will be similar to each other.

And size of rectangle that is image is
`(2)/(18)=(1)/(9)` of the Original rectangle called Pre image.

So, option A, Divide the area of original rectangle by 9, that is dilation factor of
`(1)/(9)` has taken place.

Divide them by nine.
