What are applying the rule repeatedly across several strips?
Show answer
One trapezium is a rough estimate, because a single straight line across the top cannot follow a curve that bends in and out. The fix is to use more strips: divide the baseline into several equal strips, measure an offset at every division, and treat each strip as its own trapezium. Adding the trapezia gives a much better estimate, because each short straight top hugs the curve more closely.
