a. true

b. false

Answer 1

B false
It is not a reliable source of measurement because it differ from person to person

Answer 2

(b) false.

• A hand span is not a reliable measure of length as each hand span varies from person to person.

• Since sizes vary from person to person, hand span and cubit are not considered to be standard length measurements.
• So, two different people can measure the same length differently, which is undesirable for a standard unit.
• The standard units of length are the kilometer (km), the meter (m), and the centimeter (cm).
• These units have standard measurements, and are converted using specified formula.
• Additionally, the units of length in the conventional system (used in the United States) include inches, feet, yards, and miles.
