Given : a diagonal scale of R.F.=1/25000 to read centimetres up to 5 Km and on it
To Find : show length 3.48 KM.
Solution:
1 cm on scale = 25000 cm in actual
=> 1 cm on scale = 250 m in actual
=> 1 cm on scale = 0.25 km
0.25 km in actual = 1 cm
=> 1 km in actual = 4 cm
=> 5 km in actual = 20 cm
Scale from 0 to 20 cm
3.48 km = 3.25 km + 0.13 km
= 0.25 * 13 + 130 m
= 13 main divisions + 125 m + 5 m
= 13 main divisions + 5 x 25 + 5/25 *10
= 13 main divisions + 5 sub divisions + 2 sub sub division
