Answer 1

The unit of measure that represents a value that is 10 times the base unit meters is decameter (da).

Here’s how the prefixes work in this case:

• Base unit (meters): 1 meter
• Decameter (da): 10 meters
• Hectometer (h): 100 meters
• Kilometer (k): 1,000 meters
• Decimeter (d): 0.1 meters (or 1/10 of a meter)
• Centimeter (c): 0.01 meters (or 1/100 of a meter)
• Millimeter (m): 0.001 meters (or 1/1,000 of a meter)

Thus, the right choice is decameter.
