1.6 B 1.7 A 1.8 A 1.9 C 1.10 B

3. MAGNETIC BEARING
2.1
Magnetic bearing = Geographic bearing + Mag. declination
Geographical bearing = 192°
192°
Mean magnetic declination 25°29’ West of true North (2001). Mean annual change 9’ Westward. WN MN
Magnetic declination for 2010:
25°29’W + 81’ W = 26°50’ W
Magnetic bearing for 2010:
192° + 26°50’ W = 218°50’W

4. GRADIENT = 1:31,2 FORMULA: Gradient = VI (Difference in height)

7. AREA Area = Length x Breadth FORMULA 3,6cm Distance x Scale 100 000
2.7
Area = Length x Breadth
FORMULA
3,6cm
Distance x Scale
= 3,6 x
= 1,8km
LENGTH
Distance x Scale
= 3,0 x
= 1,5km
BREADTH
