Math Help - Simple area under curve problem

1. Simple area under curve problem

Hi guys (and gals). I'm a little confused on this problem, specifically where to start drawing the rectangles, and what the widths would be. Here is the problem blank, then what I have attempted later:

Here is how I have attempted to begin,I am not sure if this is correct...

I would use trapeziums instead of rectangles for greater accuracy. You can then use the trapezium rule to estimate the area under the curve.

If your teacher tells you to use rectangles then you're on the right path. Work out the area of each and add them up

Yeah, but I was wondering if I did the widths and drawing correctly?
