Areas are already of the type that are measured in squared units of length.
Milliliters is a measure of volume and 3000cm squared is a measure of area, hence the question is not meaningful.
No. A metre measures length, a squared metre measures area.
A centimetre squared is a measure of area; it can have any shape. The easiest area of 1 centimetre squared (to draw/visualise) is a square with one centimetre on each side.
The area of the square is the measure of the side squared.
circle area is pi times radius squared
289in squared
It is its square area which is found by pi*radius squared
It is its square area which is found by pi*radius squared
It is its square area which is found by pi*radius squared
square inches is a measure of area, your question - as phrased - makes no sense.
Nothing. A squared metre is a measure of area. A kilogram is a measure of mass. The two measure entirely different things and it makes no sense at all to try to convert from one to the other.
To measure the area of a square, you can multiply the length of one side by itself (squared). The formula for the area of a square is side length squared (A = s^2). This will give you the amount of space enclosed by the square in square units.
