Detailed explanation-1: -These are called the base quantities for that system and their units are the system’s base units. All other physical quantities can then be expressed as algebraic combinations of the base quantities. Each of these physical quantities is then known as a derived quantity and each unit is called a derived unit.
Detailed explanation-2: -Area, speed, volume, force, etc are examples of derived quantities.
Detailed explanation-3: -A derived unit is a unit that results from a mathematical combination of SI base units. Calculations involving derived units follow the same principles as other unit conversion calculations.
Detailed explanation-4: -Derived quantities are the quantities that can be derived from fundamental quantities. Example: speed is a derived quantity. It can be derived from fundamental quantities, length and time.
