Calculate Numerical Values: First, we need to calculate the numerical values for $15\sqrt{2}$ and $14\sqrt{2}$ .
Sum Up Lengths: Next, sum up all the lengths of the rods: $12 + 13 + 14 + 21.2 + 17 + 12 + 11 + 15 + 16 + 19.8$ .
Find Mean: Now, divide the total length by the number of rods to find the mean.
