What is the scale factor of a house if 1/4 square inch is equal to 5 ft (1 sq. Inch= 20 sq. Feet)

Question

I understand the topic but I just can’t figure this out :(

Answer 1

Assuming 1/4 in² = 5 ft²

1/4 in² = 5(144) in²

 

The ratio of area is as the square of the linear ratio.

 

1/2 in = 12√5 in
