Answer 4

I can help with this. @jpdogw: first, would you please explain what "inscribed rectangle" means to you, and perhaps actually draw the 3 inscribed rectangles in the illustration below?

Answer 5

The math content of this question leads up to "Riemann Sums" in Calculus, so the problem must be done using "inscribed rectangles." We'll add up the areas of the three "inscribed rectangles" to approximate the total yellow area.
