The average home size was 3,500 square feet.
Answer:
3,500 feet²
Step-by-step explanation:
The average home size in United States in 1970 was 1,400 square feet.
The average size was about [tex]\frac{5}{2}[/tex] times great in 2004.
The difference in size of home = [tex]\frac{5}{2}\times 1,400[/tex]
= [tex]\frac{7,000}{2}[/tex]
= 3,500 square feet.
The average home size was 3,500 square feet in 2004.
