Step-by-step explanation:
Given that:
Dimension of Original photo = 4 inches by 6 inches
Intended dimension of model = 3 feet by 4 1/2 feets
Converting from feets to inches :
1 foot = 12 inches
Therefore,
Intended dimension of model :
3 feets = (3 * 12) = 36 inches
by 4 1/2 feets = (4 1/2 * 12) = 54 inches
Hence, scale factor required :
36 /4 = 9
54 / 6 = 9
Scake factor = 9
