What will the new dimensions of the rectangle be after a dilation with a scale factor of 7/8?

Answer 1

Each dimension of the image rectangle will be 7/8 times the corresponding dimension on the original rectangle.

Example, Suppose the original rectangle is 8 by 4. After dilation, the dimensions of the image rectangle will be:

(7/8 · 8) by (7/8 · 4) = 7 by 7/2.
