Accepted Solution
A:
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
