  1. The amount of fertilizer required to apply to a lawn area of 175 m2 is approximately 4.9 kg.





  2. A lawn of approximately 70 m2 is needed for 2 kg of fertilizer.

  3. The value of 270 m2 is not part of the graph, so extrapolation must be used (the line must be extended).




    The amount of fertilizer required can be estimated by using the graph.




    The amount of fertilizer required for a lawn area of 270 m2 is approximately 7.6 kg.
