Solution:

Scale is the representation of ratio of lengths in the drawing to the actual length.

The scale given here means that 1 inch length in the drawing corresponds to 6 feet length actually.

Thus, in order to find the actual length of 3 inches, we can use unitary method

If 1 inch in drawing corresponds to  = 6 feet
