${\huge{\blue\longrightarrow{\texttt{\orange A\red N\green S\pink W\blue E\purple R\red}}}}$

According to question:-

$= {(5 + 3 \sqrt{2}) }^{2}$

${(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy$

$= {(5)}^{2} + {(3 \sqrt{2} )}^{2} + 2 \times 5 \times 3 \sqrt{2}$

$= 25 + 18 + 30 \sqrt{2}$

$= 43 + 30 \sqrt{2}$
