The original painting is:
$203.2 cm$ x $152.4cm$
or
$2.032 m$ x $1.524m$

Explanation:

First we need to convert all units to the same system. 1 inch is equal to $2.54 cm$ , so we multiply each inch by $2.54$ to get the measurements of Marie's copy in centimeters.

$2*2.54=5.08 cm$
$1.5*2.54=3.81cm$

Now when it says that the scale is 1 in 40cm (1:40) it means that each centimeter in the copy represents 40 in the original. So we multiply our results by 40 to get the original size.

$5.08 *40 = 203.2 cm$
$3.81*40=152.4cm$
