Question

Draw a linear scale to show 10 km and primary division is 5 km and secondary division 1 km and r.f = 1:200000

Answer 1

Answer:

1 cm on the map represents 10 km on the ground.

15 cm on the map represents on the ground

= 10 × 15 = 150 km.

(The normal length of scale should be 15 cm) 150 km is a round number. Therefore we not select any other number.

Scale 1 cm : 10 km.

1 cm on the map represents 10 km on the ground.

15 cm on the ma

Fig. 2.5.

Construction. Draw a line 15 cm long. Divide it into 15 primary divisions. Each division represents 10 km. Sub-divide the left hand divisions into five secondary divisions, each showing a distance of 2 kms.
