Question

Sean is creating a series of rectangles, one inside the other. The length of the first rectangle, Rectangle A, is four inches. Sean dilates Rectangle A about its center by a scale factor of two to get Rectangle B. He repeats this process using the same scale factor till he gets a rectangle of length 32 inches.

How many dilations did Sean perform including the dilation of Rectangle A?

Answer 1

I think it's 5

Answer 2

a to b gives length of 8. Next, 8 to 16 then 16 to 32. so he did it 3 times
