Construct a Simple scale of 1:5 to show decimeters and centimeters and to read upto 1 metre. Show the length of 7.4 decimetres on it.

i) The scale has to represent decimetre and 1/10 of decimeter.

ii) Given that the scale is 1:5 that is R.F=1/5

iii) Maximum length to read is 1 metre; Length of the scale=(1/5)x1x100=20cm.
