And the first thing I'm tackling is understanding the area of a shape by inscribed/circumscribed polygons.(adsbygoogle = window.adsbygoogle || []).push({});

For example, the shape produced by the line: y = x + 1, the y axis, and the vertical line x = 2.

Now, my understanding is that the area is the limit as n approaches infinity of the sum of the area of n inscribed rectangles.

Can someone explain how this translates to actual math? How would I find the area of the above shape?
