Definition
area formula defines the region as a trapezoid lying on its side, with terms involving x and limits of integration on the x-axis.
Mechanism
area formula The region is a trapezoid lying on its side, so we can use the area formula for a trapezoid A = (a + b)h, where h represents height, and a and b represent the two parallel sides. We know the base is a square, so the cross-sections are squares as well (step 1).
Effects
area formula defines the area in terms of x, with integration limits constrained to the x-axis.
