Hey there,
area of a trapezium = 1/2 (b + a) h
where a and b are parallel sides and h is the altitude or distance between a and b.
In a canal, the floor of canal and the top water surface are parallel. Height of trapezium is the depth of canal.
84 meters = 1/2 ( 12 + 8) Height
Height = 168/20 = 8.4 meters
Hope this helps!
