Study the map extract on a scale of 1:50,000 and attempt the following questions :
(a)(i) In your answer booklet draw to one third, the original scale, an outline of the map (ii) What is the scale of the outline drawn?
(b) On your outline, show (i) the settlement of Okeigbo and Omifunfun (ii) a ridge east of Okeigbo (iii) River Oni and its direction of flow (iv) the minor road from ldare Omifunfun
(c) State two reasons why Okeigbo could be considered more important than Mafoworade
(d) State any land-use types found in the area
(a)(i) Outline of the map reduced to one-third of the original scale
The extract is redrawn so that every length is reduced to one-third of its length on the original map, while the shape, orientation and relative positions of all features are kept exactly the same. The reduced outline, with the required features added for part (b), is shown below.
One-third reduction of the map extract (scale 1:150,000) showing the settlements of Okeigbo and Omifunfun, the ridge east of Okeigbo, River Oni with its direction of flow, and the minor road from Idare to Omifunfun.
(a)(ii) Scale of the outline drawn
The original scale is 1:50,000, meaning 1 unit on the paper represents 50,000 units on the ground. When every distance on the paper is reduced to one-third, the same piece of ground is now shown by a paper length that is three times smaller, so each paper unit must represent three times as much ground:
\[ 50{,}000 \times 3 = 150{,}000 \]
The scale of the outline drawn is therefore 1:150,000 (that is, 1 cm on the outline represents 1.5 km on the ground).
(b) Features shown on the outline
The following are marked and named on the reduced outline above, each in its correct relative position taken from the extract:
(i) The settlements of Okeigbo and Omifunfun, each shown by a small settlement circle and named. Okeigbo is drawn as a nodal point where several roads converge.
(ii) The ridge east of Okeigbo, shown by its elongated pattern of closed contour lines running roughly north-south, with the crest marked.
(iii)River Oni, drawn as a single line with an arrow indicating its direction of flow (from the higher ground in the north-east towards the lower ground in the south-west).
(iv) The minor road from Idare to Omifunfun, drawn as a double broken line and labelled.
(c) Two reasons why Okeigbo could be considered more important than Mafoworade
Superior services and administrative functions: Okeigbo possesses a hospital, a district council office, a police station, schools and a piped water supply, whereas Mafoworade has none of these facilities. This concentration of social and administrative services makes Okeigbo a higher-order central place.
Greater accessibility as a nodal town: Okeigbo is a route centre where several roads meet, giving it far better accessibility for trade and movement of people and goods, while Mafoworade lies off the main route junctions and is far less accessible.
(d) Land-use types found in the area
(i) Farming (agriculture): shown by the widespread areas of scattered cultivation across the mapped area.
(ii) Transportation: shown by the presence of all categories of roads (main roads, minor roads and tracks) linking the settlements.
(iii) Settlement: shown by the several settlements such as Okeigbo, Omifunfun and others, each performing different functions.

The extract is redrawn so that every length is reduced to one-third of its length on the original map, while the shape, orientation and relative positions of all features are kept exactly the same. The reduced outline, with the required features added for part (b), is shown below.
One-third reduction of the map extract (scale 1:150,000) showing the settlements of Okeigbo and Omifunfun, the ridge east of Okeigbo, River Oni with its direction of flow, and the minor road from Idare to Omifunfun.

\[ 50{,}000 \times 3 = 150{,}000 \]
