Answer 1

$\large\boxed{\begin{array}{l}\underline{\rm Per\acute imetro\,de\,um\,ret\hat angulo}\\\underline{\rm de\,dimens\tilde oes\,a\,e\,b}\\\huge\boxed{\boxed{\boxed{\boxed{\sf P=2\cdot(a+b)}}}}\end{array}}$

$\Large\boxed{\begin{array}{l}\sf No\,problema~a=8y~~b=3x\\\sf P=2\cdot(a+b)\\\sf P=2\cdot(8y+3x)\\\sf P=16y+6x\longrightarrow resposta\end{array}}$
