Final answer:
Appropriate units for creating a crime scene sketch include meters, feet, and yards. The choice depends on the scale and nature of the crime scene, with kilometers being too large for most crime scene sketches.
Step-by-step explanation:
When creating a crime scene sketch, acceptable units of measurement include meters, feet, and yards. Kilometers are typically used to measure longer distances, such as between multiple locations or around a large block. Meters are generally used for closer objects, like the length of a house or a pool. Meanwhile, feet can be an appropriate measure for indoor scenes, such as the length of a room, where using yards or meters might seem too substantial for detailed work. Yards can be used for outdoor scenes where distances between objects are not extensive, akin to measuring between houses or sidewalks. Thus, the most appropriate unit would depend on the nature and scale of the scene.
