    theres 2 ways u can do it, the first is to use right end points and use bars on y axis instead of x axis, and then doing the same with elft endpoints, and averaging them out to get an approximate area.

    i would use rectangles at each value of x (incremented), so at 1, 2,3,4,5,6,7,8.. did u see how to do that?

    ok, so lets do it step by step. draw out ur graph, which is basically x^2, with every y value multiplied by 2.

    then u draw rectangles (horizontally from every y value up to 8, where the top line ends at the curve,

    do u have ur textbook? because it will explain with details and images how to do it in there, its very hard to explain without a diagram to show you.
