How can we estimate how much land will be lost over a period of time?
There is a variable rate of land erosion at different points on the coastline. How can we estimate how much land will be lost over a period of time? 3

Reflect on your work What is the trapezium rule formula?
Explain the role of the various factors in this formula. What would you need to do to have more accurate estimates? Describe how you can use the trapezium rule to estimate land loss due to coastal erosion.
