Area and Volume – The Trapezoidal Rule

Use the Trapezoidal rule to estimate the area of the field. The area of the same field was re-estimated by applying the Trapezoidal rule again. This time, a different section width (4 m) and a different set of section heights were used, as shown below. The area was found to be 145∙6 m2.

How to Approximate Area with the Trapezoid Rule

With the trapezoid rule, instead of approximating area by using rectangles (as you do with the left, right, and midpoint rectangle methods), you approximate area with — can you guess? — trapezoids. Because of the way trapezoids hug the curve, they give you a much better area estimate than either left or right rectangles. And […]
