The dimensions of the famous painting are 80cm * 60cm.

Explanation:

The famous painting of René Magritte has a particular set of dimensions but since it's a bit large Marie scales it down to a smaller size. Marie's scaled-down version of the painting measures 2" x 1.5".

The scale of her copy is 1 inch to 40 cm which means that every inch drawn on Marie's drawing is 40 cm on the original painting.

So to find the dimensions of the original painting we convert each inch inot 40cm.

2" = 2 inches = 2 * 40 cm = 80 cm.

1.5" = 1.5 inches = 1.5 * 40 = 60 cm.

So the original painting had the dimensions 80cm * 60cm.
