Question

Rectangle Q has an area of 2 square units. Thea drew a scaled version of Rectangle Q and labelled it Rectangle R.

What scale factor did Thea use to go from Rectangle Q to Rectangle R?

Rectangle R is 8 by 9

Answer 1

Explanation:

It is given that Rectangle Q has an area of 2 square units.

Thea Drew a scaled version of Rectangle Q and marked it as R.

As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.

As you have not written what is the scale factor of transformation

Suppose , Let the Scale factor of transformation= k

Rectangle Q = Pre -image, Rectangle R= Image

If, Pre-Image < Image , then scale factor is k >1.

But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.
