GEOGRAPHY PRACTICAL ANSWER

___________________________________________________________

(1a)

Old scale = 1:50, 000

New scale = 1:150,000

Map scale = ?

Map scale = old scale/new scale 

= 50,000/150,000

=1/3

New length = 36.5 * 1/3 = 12.2cm

New width = 37*1/3 = 12.3cm 

The map is a reduction and should be reduced to a third of its original size. 

(1b)

Length of minor road from Marabu to KARLAHI = 15.5cm * 150,000/100,000

= 23.3km

(1c)

(i) With evidence on the map, the presence of schools at KARLAAHI settlement indicate socio-economic functions.
