In the SI, these units are derived from other units. For example, an area is a length squared. Of course, it is possible to proceed the other way round, for example to define an area as the base unit, in which case a length would be the square root of an area. That looks more complicated, but it's possible. Thus, whether a unit for a specific type of measurement is a base unit or a derived unit really depends on the system of units selected.
It is area and density.
Area is length x length, or length squared.
There are no S.I. base units for area or volume because they are derived quantities, calculated from base units. Area is derived from the square of length (meters squared), and volume is derived from the cube of length (meters cubed). The S.I. system focuses on a limited set of base units to maintain simplicity and consistency, allowing for a wide range of derived units to be expressed in relation to these fundamental measurements.
Yes, area is a derived quantity.
The [human] population density.
It is area and density.
Some examples of derived quantities are velocity (which is derived from distance and time), acceleration (derived from velocity and time), density (derived from mass and volume), and pressure (derived from force and area).
the quantities that are expressed in term of base quantities are called derived quantities e.g area volum speed force energy
An area, in its simplest form is derived by multiplying together two lots of the basic quantities - lengths.
Area and speed are derived quantities because they are obtained by combining base quantities. Area is derived from multiplying two length measurements, while speed is derived from dividing a length measurement by a time measurement. These derived quantities are built upon the fundamental base quantities of length and time.
Derived quantities are quantities that are calculated from two or more measurements. They include area, volume, and density. The area of a rectangular surface is calculated as its length multiplied by its width. The volume of a rectangular solid is calculated as the product of its length, width, and height.
Area is length x length, or length squared.
Basic or fundamental quantities are seven in number. They cannot be derived right from one another. Hence they are independent. They are length, mass, time, electric current, temperature, quantity of substance, luminosity. Two sub are there. They are plane angle and solid angle. But derived are many in number. Just by the name they are derived right from the fundamental. They are area, volume, velocity, acceleration, force, momentum, magnetic induction, electric field, dipole moment, pressure, density etc etc

Derived quantities are physical quantities that are calculated from one or more base quantities using mathematical operations. These derived quantities are not independent and depend on the base quantities for their definition. Examples include velocity (calculated from distance and time) and acceleration (calculated from velocity and time).
They are used to measure quantities that are not basic. Length, for example, is a basic unit, but area and volume are not so derived units will be used to measure area and volume.
These quantities are referred to as physical quantities in the field of physics. They are measurable properties that can be described using mathematical values and units. Area and volume are examples of scalar physical quantities, while velocity is an example of a vector physical quantity.
