In $2010$ a particular factory produced computer hard drives at a rate of f$($t$)=4\mathrm{.}2$e$0\mathrm{.}0173$t thousand drives per month where t is the time in months after the start of that year. In $2011$ the production rate was g$($t$)=5\mathrm{.}2$e$0\mathrm{.}0164$t thousand drives per month t months after the start of that year. Compute the area between the graphs of these functions for $0<=$ t $<=12.($Round your answer to three decimal places.$)$
