Given: width of the picture =60 cm

length of the picture =1.8m =180 cm
Perimeter of the picture =2 x (180+60) cm =480 cm
The ratio of its width to its perimeter = \frac{\text { Width of the picture }}{\text { Perimeter of the picture }}=\frac{60 \mathrm{~cm}}{480 \mathrm{~cm}}=\frac{1}{8}\Rightarrow 1: 8

Option D is correct.
