Divide the length of the object on the drawing by its actual size to find the scale:

$\frac{2\text{ inches}}{18\text{ feet}}$

Since each feet has 12 inches:

$\frac{2\text{ inches}}{18\text{ feet}}=\frac{2\text{ inches}}{18\cdot12\text{ inches}}=(2)/(216)=(1)/(108)$

Therefore, the scale used in the drawing is 1:108 (one inch in the paper equals 108 inches in real life).
