Final answer:

The length of the object in the drawing is 2.25 cm.


Step-by-step explanation:

To find the length of the object in the drawing, we can use the scale provided. The scale is 1 cm = 2 in. This means that for every 1 cm in the drawing, it represents 2 inches in reality.

If the actual length of the object is 4.5 inches, we can set up a proportion:

1 cm / 2 in = x cm / 4.5 in

Cross-multiplying, we get:

2 in * x cm = 1 cm * 4.5 in

x cm = (1 cm * 4.5 in) / 2 in

x cm = 2.25 cm

Therefore, the length of the object in the drawing would be 2.25 cm.
