we know that
The scale drawing is
1 in=16 ft
To find out the actual area convert the dimensions of the model to feet
so
Multiply by the scale factor
4 in=4*16=64 ft
3 in=3*16=48 ft
2 1/4 in=2.25 in=2.25*16=36 ft
1 3/4 in=1.75 in=1.75*16=28 ft
Find the area of the room in square feet
so
the area is equal to
(64*28)+(36)*(48-28)=2,512 ft^2
therefore
the approximate area is the option A
