Let $A$ denote the area of the shaded region shown below.  We can approximate the exact area $A$ using the following Riemann sums. $L(3)$ is the left-hand rule with $3$ equal subdivisions. $R(3)$ is the right-hand rule with $3$ equal subdivisions. $L(6)$ is the left-hand rule with $6$ equal subdivisions. $M(6)$ is the midpoint rule with $6$ equal subdivisions. $R(6)$ is the right-hand rule with $6$ equal subdivisions. **Put these five approximations in order from smallest to largest.** [[☃ sorter 1]]
