Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    How many metres make a kilometre, and how many square metres make a hectare?

    Model answer

    1 000 m make a kilometre and 10 000 m² make a hectare.

  2. 2

    How is the area of a rectangular field measuring 40 m by 25 m worked out?

    Model answer

    The two sides are multiplied together, giving 1 000 m².

  3. 3

    What does a scale of 1:10 000 mean in words?

    Model answer

    One centimetre measured on the map stands for 10 000 cm, which is 100 m, on the ground.

  4. 4

    Which is the larger scale map, 1:10 000 or 1:100 000?

    Model answer

    The 1:10 000 map, because it covers a smaller area in far greater detail.

  5. 5

    How many square kilometres are 250 hectares?

    Model answer

    2.5 km², because 100 hectares make one square kilometre.

  6. 6

    What is a data collection sheet?

    Model answer

    A table or form prepared before going out so that every reading is recorded in the same way and nothing is missed.
