The rectangles in the graph below illustrate a right endpoint Riemann sum for $f(x)=(\frac{17}{x})$ on the interval $[3,7].$

The value of this right endpoint Riemann sum is $,$ and this Riemann sum is $$ the area of the region enclosed by $y=f(x),$ the x $-$axis, and the vertical lines $x=3$ and $x=7.$
