Answer 1

Answer:

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
