(a) Draw an outline of the map using a scale of 1:300,000. To reduce the map thrice its size,
Length = 37.5cm ÷ 3 = 12.5 cm.
Breadth = 36.6cm ÷ 3 = 12.2cm.
If the original scale of the map is 1:100,000; therefore, the reduced scale will then be
1:100,000 x 3
= 1:300,000. (This is the scale of the new outline).
(b) Drainage features found on the map:
(i) meanders
(ii) watersheds
(iii) floodable plains
(iv) Braiding
(v) River valley
(vi) Dendritic drainage pattern
(c) Human and physical features found along the road.
Human features: Include, settlements, bench marks, scattered cultivation, wells and footpaths.
Physical features: Include, scrub, plain, hill and river valley.
