Calculation of area of irregular plane surfaces

Problems
1) Find out the area of the land show in fig, using Simpson’s rule (All measurements are in m.)

fig5


A = h/3 {Y1+Yn+ 4 (Y2+Y4+Y6+Y8+Y10)+ 2 (Y3+Y5+Y7+Y9+Yn-1) }

= 4/3 [7.2+ 0 + 4 (9.4+11.9+11.6+8.6+3.2) + 2 (11+12.1+10.5+6.2)]
= 354.13m2
