Measurement in math is the act of finding the length, width, height etc... of a certain object, different measurement schemes are used for different objects.
eg:
Centimetres for small shapes, Square centimetres for area Centimetres cubed for volume.
There are different ways of measuring geometric shapes, depending on the dimentional qualities of them. For example, measuring a line ----- long, you could count how many dashes there are, and call it 5 dashes long, or you could measure it with a ruler.
But for something like:
------- I I I I -------
You would first use the formula for Area to get the inside size, or use the formula for perimeter. A=LW for a square, So Area = Length * Width
So as
Which is 28cm squared
For perimeter in a square, you take each side and add them together. So
