calculista
we know that
[scale]=[doll house]/[real house]
[scale]=12 in/3 ft

The living room in stacy's house is 18 feet by 12 feet
so
for 18 ft
 [doll house]=[scale]*[real house]-----> (12/3)*18--------> 72 in

for 12 ft
 [doll house]=[scale]*[real house]-----> (12/3)*12--------> 48 in

The living room in doll house is 72 in by 48 in
The living room area in doll house is (72*48)-----> 3456 in²

Tom will need for the living room in Stacy's doll house 3456 in² of carpeting

the answer is 3456 in² of carpeting
