Answer:
The length of the ladder would be 32 feet.
Step-by-step explanation:
In order to find the missing value, we create a proportion. We can do this by making two fractions -- the numerator being the depicted length and the denominator being the actual length.
(1.5/4) = (12/x)
Since we don't know the actual length of the ladder, we put it in as x. Now we can cross multiply to solve.
(1.5/4) = (12/x)
1.5*x = 4*12
1.5x = 48
x = 32
