Answer:
Width\breadth of picture = 60 cm
Length of picture = 1.8 m = 180 cm
Let P is the perimeter , l is length and b is breadth then
P= 2(l+b) = 2( 60+180) = 480P=2(l+b)=2(60+180)=480
Now ratio of width to its perimeter is given by
\dfrac{width}{perimeter} =\dfrac{60}{480} =\dfrac{1}{8}perimeterwidth=48060=81
Hence, the required ratio is 1:8
