Question

The diagram represents the enlargement of a rectangle by using a scale factor of 6

Answer 1

If you're are looking for the dimension of the pre-image, I believe it would be 30. For the enlarged rectangle, 30•6= 180. Just divide 180 by the scale factor, 6, and that gives you 30. I hope this helps! :) 

Answer 2

The answer is 5 ft by 1 foot
