# Programmed Math/Measuring

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 ${\displaystyle 4*7=28cm^{2}}$

Which is 28cm squared

For perimeter in a square, you take each side and add them together. So ${\displaystyle 4+4+7+7=2*4+2*7=8+14=22}$
