Answer 1

Answer:

12 cm

Step-by-step explanation:

You would only have to focus on the green line and then you just have to divide it by 12 and you get 4 and than you multiply 3 cm by 4 and the answer for the actual length of the green line will be 12 cm.

Answer 2

Answer:

12 cm

Step-by-step explanation:

The ratio of feet to cm is 12:3. Set up a ratio to find the length of the green line in cm.

12 feet ÷ 3 cm = 48  ft ÷ x

Cross multiply and divide.

3 x 48 = 12 × x

144 = 12x

x = 12

The actual length of the green line is 12 cm.

Hope that helps.
