Answer 1

$Hola~~~~ \\ \\ h~\boxed{\Bigg|~~~~~~~~~~~~~} \\~~~~~~~~~~~ \frac{2}{7}h \\ \\ 2h+2( \frac{2}{7}h)=27 \\ \\ 14h+4h=189 \\ \\ 18h=189 \\ \\ \boxed{\boxed{h= 10,5cm}}~---\ \textgreater \ altura \\ \\ ======================================\\ base= \frac{2}{7}\underbrace{h}_{10,5} \\ \\ base= \frac{2.(10,5)}{7} \\ \\ \boxed{\boxed{base=3cm}} ~--\ \textgreater \ base \\ \\ \mathbb{iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii} \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Saludos!!$
