1. **State the problem:** We need to find the length of a line on a scale drawing where 1 cm on the drawing represents 64 cm in real life. We are given real distances and must convert them to the drawing scale.
2. **Formula:** The length on the drawing is given by
$$\text{Drawing length} = \frac{\text{Real length}}{\text{Scale factor}}$$
where the scale factor is 64 cm per 1 cm.
3. **Calculate each length:**
(5) For 224 cm:
$$\frac{224}{64} = \frac{\cancel{224}}{\cancel{64}} = 3.5 \text{ cm}$$
(6) For 32 cm:
$$\frac{32}{64} = \frac{\cancel{32}}{\cancel{64}} = 0.5 \text{ cm}$$
(7) For 352 cm:
$$\frac{352}{64} = \frac{\cancel{352}}{\cancel{64}} = 5.5 \text{ cm}$$
(8) For 440 cm:
$$\frac{440}{64} = 6.875 \approx 6.9 \text{ cm}$$
4. **Final answers rounded to the tenths place:**
- (5) 3.5 cm
- (6) 0.5 cm
- (7) 5.5 cm
- (8) 6.9 cm
These are the lengths needed on the drawing to represent the given real distances using the scale 1 cm = 64 cm.
