Use left and right endpoints and the given number of rectangles to find two approsimations of the area of the region between the graph of the funct on and the xoaxis over the given interval, \[ f(x)=2 x+9, \quad[0,2], \quad 4 \text { rectangles } \] \[ <\text { Area }< \] Use left and right endpoints and the given number of rectangles to find two approximatians of the area of the regiun between the graph of the function and the n-wxis over the given interval, (Round your answers to four decimal places.) \[ o(x)=5 \sin (x),\{0, \pi\}, 6 \text { rectangles } \] left endpoins approximation Areas right endpoints approximation Area:
