\

The tallest doll is $\"\"$ .

\

Heights are scaled by a scale factor of $\"\"$ .

\

Find the heights of the next tallest doll.

\

$\"\"$

\

$\"\"$

\

Height of the next tallest doll is $\"\"$ .

\

2)

\

First rectangle length and width is $\"\"$ and $\"\"$ .

\

Consider the scale factor as ratio between length and width is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Second rectangle lenght and width is $\"\"$ and $\"\"$ .

\

Consider the scale factor as ratio between length and width is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ .

\

$\"\"$

\

Third rectangle lenght and width is $\"\"$ and $\"\"$ .

\

Consider the scale factor as ratio between length and width is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ .

\

$\"\"$

\

Therefore, First and third rectangles are similar.
