The new side will measure;
3/2*3
=9/2
=4.5 inches

Answer:

[tex]4\frac{1}{2}in[/tex]

Step-by-step explanation:

We know that one side of the original is

[tex]1\frac{1}{2}in[/tex]

Also, the copy machine enlarges the original by a scale factor of three. This means that the enlarged result is three times bigger that the original. Remember that a scale factor multiplies the original measure.

So, the bigger copy would be

[tex]3\times 1\frac{1}{2}in=3 \times \frac{3}{2}=\frac{9}{2}=4\frac{1}{2}in[/tex]

Therefore, the image changed from [tex]1\frac{1}{2}in[/tex] to [tex]4\frac{1}{2}in[/tex].
