Question

Rectangle $Q$ has an area of two square units. Thea drew a scaled version of rectangle Q and labeled it rectangle R. what scale factor did Thea use to go from rectangle Q to rectangle R?

Answer 1

Step-1: Given data.

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

Step-2: To find the scale factor used.

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

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

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,$0<k<1.$
