The Answer is 54. (C.)

To find the actual length of the dog, you need to scale up the given measurement based on the provided scale.

Given:
Length on scale drawing = 9 cm
Scale = 1 cm : 6 cm

To find the actual length:
Step 1: Set up the proportion using the scale.
Scale length / Actual length = Scale factor
1 cm / Actual length = 6 cm / 9 cm

Step 2: Cross multiply and solve for the actual length.
9 cm * 1 cm = 6 cm * Actual length
9 cm = 6 cm * Actual length
Actual length = 9 cm / 6 cm
Actual length = 1.5 cm

Therefore, the actual length of the dog is 1.5 cm.
