Given:

shape: rectangle

length: 1200 mm

width: 800 mm

Find: area in square meters

Solution:

First, let's convert the given dimensions to meters.

Conversion rule is 1 m = 1000mm. Let's convert the length first.


1200\operatorname{mm}*\frac{1m}{1000\operatorname{mm}}=1.2m

Length = 1.2 meters

Now, let's convert the width.


800\operatorname{mm}*\frac{1m}{1000\operatorname{mm}}=0.8m

Width = 0.8 meters

Now that we are done converting the dimensions of the board to meters, let's solve for the area. The formula is:


Area=length* width\text{ }

Let's plug in the converted dimensions to the formula.


Area=1.2m*0.8m=0.96m^2\text{ }

Therefore, the area of the board is 0.96 square meters.
