1. The problem states that the scale of the office plan is 1:200, meaning 1 unit on the plan represents 200 units in real life. 2. The actual length of the wall is 5.8 meters. To find the scaled length, we divide the real length by the scale factor. 3. Convert 5.8 meters to centimeters since the options are in centimeters: $$5.8\text{ m} = 580\text{ cm}$$ 4. Calculate the scaled length: $$\frac{580\text{ cm}}{200} = 2.9\text{ cm}$$ 5. Therefore, the scaled length of the wall on the plan is 2.9 cm.
