Q2) Construct a scale of 1:5 to show decimeters and centimeters and to read up to 1 meter. Show the length of 7.6 dm on it.
Sol) Given data:
RF = 1/5
Max Length (ML) = 10 dm (1 m =10 dm) ;( no. of parts of scale (n) =10 parts)
Length of scale (LOS) = RF X ML = 1/5 X 10 X 10 cm (1 dm=10cm) = 20 cm.
The length of the line that is drawn on the drawing sheet is 20 cm
