A picture is wide and long. The ratio of its width to its perimeter in lowest form is
Before we find the ratio, it is necessary to make sure that the width and the length are in the same unit.
Either convert both of them into centimetres, or both of them into metres.
Thus, we have the length of the picture to be and the width to be .
Also, the perimeter of the picture is .
Thus, the ratio of the width of picture to its perimeter is
The correct option is (d)
