Question 6 The area, A of a figure defined by some points, P1 and P2..., can be calculated from the coordinates of those points, using any of the following formulae:

A=1 / 2 D\left(E i, N_{i+1}-E_{i+1}, N i\right) Where Ei and Ni are the easting and northing coordinates of the point Pi.The following table shows the coordinates to three points A, B and C. Difference = Divide by 2=
