I am trying to get the area (m2)of this diagram and I cant seem to get the hang of it.
the first triangle on the left I do the following:
1/2*BASE*HEIGHT or 1/2*8*(8+16.3) = 97.2 m2
Then I go for the next one:
1/2*BASE*HEIGHT or 1/2*(8+16.3)*10.3 = 125.15
Then I go for the trapezium:
Height*sum of parallel sides or 8.6*(19.3+9) = 243.38
The sum of that = 465.73
Now my text book confirms that that is dead wrong, need some help all, am flustered over this.
