Question 1 WAEC_MODEL_QUESTIONS_VOL1 • 2022 • GEOGRAPHY • practical

A topographic map of a district is drawn at a scale of 1 cm : 250 m. The map shows three settlements: A, B and C. The straight‑line distances measured on the map are: AB = 6.4 cm, AC = 8.0 cm and BC = 5.0 cm. The map also shows a river that runs between points D and E, which are located on the map such that the line DE is 3.2 cm long and makes an angle of 30° clockwise from the line AB. The bearing of AB from A is 045° (measured clockwise from north).

Question Parts

( a )
Determine the actual ground distances between the settlements A–B, A–C and B–C in metres.
( b )
Using the given information, calculate the bearing of the river line DE from point A, giving your answer to the nearest degree.
( c )
The triangular region formed by settlements A, B and C is required for planning. Using Heron’s formula, compute the actual area of the triangle in square kilometres, giving the answer to two decimal places.
( d )
