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.
Yes, area is a derived quantity.
The [human] population density.
Length is fundamental, area is derived.
It is area and density.
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.
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.
derived quantities
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
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.
Base quantities (Scalar Quantities) :Independent quantities who have single standard units.- time /seconds-distance/metersDerived Quantities (Vector Quantities):Quantities derived by multiplying or dividing 2 base quantities.- Velocity = distance/timeunit of Velocity = m/s

It's because we don't measure it directly but use measurements of two lengths to compute result. Our area mesurement depends then on precision of some other measured quantities.
