Answers

We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:
$(2)/(x)$ = $(1)/(40)$
= $(2*40)/(1)$ =x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:
$(1.5)/(y)$ = $(1)/(40)$
$(1.5*40)/(1)$ =y
60 cm=y
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION
