Answer:
$0.96\ m^2$

Explanation:

We can make the conversion from milimeters to meters (Remember that
$1m=1,000\ mm$ ). Then:

$1,200\ mm$ to
:

$(1,200\ mm)((1\ m)/(1,000\ mm))=1.2\ m$

$800\ mm$ to
:

$(800\ mm)((1\ m)/(1,000\ mm))=0.8\ m$

Now, we need to use this formula for calculate the area of a rectangle:

A=lw

Where "l" is the lenght and "w" is the width.

Knowing that:

$l=1.2\ m\\w=0.8\ m$

We can substitute values into the formula. Then we get:

$A=(1.2\ m)(0.8\ m)\\\\A=0.96\ m^2$
