Answer:
To find the scale of the photograph, we need to determine the ratio between the actual height of the man and the height of the man in the photograph.
First, we convert the height of the man from feet to inches:
6 feet = 6 x 12 = 72 inches
Next, we can set up a proportion:
actual height of man / height of man in photograph = scale factor
Substituting the given values, we get:
72 inches / 1.5 inches = scale factor
Simplifying, we get:
scale factor = 48
Therefore, the scale of the photograph is 1:48, which means that one inch in the photograph represents 48 inches (or 4 feet) in real life.
