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.
it is called a CUBOID
Rectangles do not have congruent lines. A square can always be called a rectangle. But a rectangle can't always be a square.

Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
An area, in its simplest form is derived by multiplying together two lots of the basic quantities - lengths.
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base Units.
It is called a base quantity.However, the distinction between a base quantity and a derived quantity is often not clear. For example, the second and metre are meant to be the base units for time and length. But the metre itself is defined in terms of the distance travelled by light, through vacuum, in 1/299,792,458 of a second. Consequently, a metre itself can be considered a derived unit.
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
Add the length and the width together. Then multiply it by two. You did it! This is also called the perimeter.
The rectangle which is equilateral is called as square.
It is called a rectangle!
no, but a square can be called a rectangle.
In order for two quantities to be in the Gold Ratio, also called the Golden Mean, then the ratio of the sum of the quantities to the larger quantity has to be equal to the ratio of the larger quantity, to the smaller one. The Mathematical value of the Golden Mean is 1.6180339887.

That is called "work"; it refers to a transfer of mechanical energy.
