Mathematics

So, we'll first convert the mixed fraction to "improper", and then sum both widths and lengths to get the perimeter.

\bf \stackrel{mixed}{4\frac{3}{4}}\implies \cfrac{4\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{19}{4}}\\\\
-------------------------------\\\\
\textit{then the perimeter will be the sum of widths and the lengths}
\\\\\\
\cfrac{19}{4}+\cfrac{19}{4}+6+6\implies \cfrac{38}{4}+12\implies \cfrac{19}{2}+12\implies 9\frac{1}{2}+12\implies 21\frac{1}{2}
