I presume you are asking for examples of geometric figures having an area of 16. OK. Here are some:
A square 4 units on each side.
A rectangle 2 units wide and 8 units long.
A triangle with a base 4 units wide and having a height of 8 units.
the units for area are always stated as a square of some units of lengths?
They are the same. They just have a different amount of significant figures. Ask your teacher if he/she counts significant figures. Some do, some don't.
The answer depends on the measurement units used for "12x12": feet, metres, yards or some exotic measure? Without that information the question cannot be answered.
It would depend on whether the question refers to 24ft*52ft or 24metres*52metres, yards or microns, or miles centimetres or some other units of linear measurement.
There are 4 significant figures. If a number has a decimal point with some zeroes, we count the total number of digits. Therefore, we count four significant figures.

No numbers can describe the area of a circle.However, any number with a square unit of some sort attached can, eg:1 square units, 2 square units, 345,432 square units, 3,467,235 square units, 56 square miles, 27 acres, 22 square kilometres, 37 hectares, ...
i think it is to measure units of a square
There are many units of pressure. Some common ones are:AtmosphereBarInches of MercuryPascalNewtons per square millimeterPounds per square inch
4 sided figures are quadrilaterals some of which are a square, a rectangle, a rhombus, a parallelogram, a kite ... etc
Area is always expressed in some unit of area. This is often some unit of length, squared - for example square meters, or square millimeters. However, there are units (such as the acre) which are not the square of a unit of length.
Density = mass/volume = 16 of some units/25 ml = 0.64 some units per ml - which is quite a useless measure if you don;t know what the units of mass are!
It is an integer value in some measurement units.
3.6 x 1.2 = 4.32, so if the units are meters, the answer is 4.32 square meters. However, if the units are inches, the answer is 0.109728 square meters. It the units in the problem are some other unit, the answer would be different.
AnswerSquare based figures were designed for the Warhammer (Old World) game, easier to form rows and columns of troops. Round bases for 40K, units don't move or fight the same way.You might see square bases in a 40K game on some of the (lesser) daemons as the models are the same between games.
Square kilometres for lakes or towns, square metres for rooms or gardens, square centimetres for pictures or sheets of paper are some common units and the magnitudes that they would be used to measure.
