Answer 1

$\Large\boxed{\begin{array}{l}\underline{\rm Per\acute imetro~do~ret\hat angulo}\\\underline{\rm de~dimens\tilde oes~b~e~h}\\\sf p=2\cdot(b+h)\\\sf p\longrightarrow per\acute imetro\\\sf b\longrightarrow base\\\sf h\longrightarrow altura\\\underline{\rm \acute Area~de~um~ret\hat angulo}\\\underline{\rm de~dimens\tilde oes~b~e~h}\\\sf A=b\cdot h\\\sf A\longrightarrow \acute area\end{array}}$

$\Large\boxed{\begin{array}{l}\tt dados\begin{cases}\sf b=25~m\\\sf h=5~m\\\sf p=?\\\sf A=?\end{cases}\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf p=2\cdot(b+h)\\\sf p=2\cdot(25+5)\\\sf p=2\cdot30\\\sf p=60~m\\\sf A=b\cdot h\\\sf A=25\cdot5\\\sf A=125~m^2\end{array}}$
