siniylev [52]

Answer:

  A) 1/45

  B) 1/60

Step-by-step explanation:

<u>Part A</u>

The actual car has a length to width ratio of ...

  length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6

The rectangle on the screen has a length to width ratio of ...

  length/width = (13 cm)/(4 cm) = 3 1/4

Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.

For a model width of 4 cm, the scale factor is ...

  model/life-size = (4 cm)/(180 cm) = 1/45

__

<u>Part B</u>

For a model width of 3 cm, the scale factor is ...

  model/life-size = (3 cm)/(180 cm) = 1/60
