since the length of the original painting is 108 inches, you take 1/12 and multiply it by 108 and get 9 inches.
the length of Sammy's drawing is 9 inches.

The length of the Sammy’s drawing was 1296 inches.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.

Scale factor = Drawing length /Actual length

In this case, you have that:

Scale factor= 1/12

Drawing length= 108 inches

So:

Scale factor = Drawing length /Actual length

1/12 = 108 /Actual length

Solving this, you get:

Actual length = 108 x 12

Actual length = 1296

So, the length of the Sammy’s drawing was 1296 inches
