Question

calcule o perímetro de cada polígono(faz as contas por favor ou sla só passa a resposta)​

Answer 1

$\Large\boxed{\begin{array}{l}\sf Para\,encontrar\,o\,per\acute imetro\,basta\\\sf somar\,todas\,as\,medidas.\\\rm a)~\sf aqui\,basta\,somar\,as\,medidas\,e\,multiplicar\,por\,2.\\\sf p=(4,5+2,5)\cdot2\\\sf p=7\cdot2\\\sf p=14\,cm\end{array}}$

$\Large\boxed{\begin{array}{l}\rm b)~\sf p= 2+4+5\\\sf p=11\,cm\\\rm c)~\sf p= 2+5+4+3\\\sf p=14\,cm\\\rm d)~\sf p=5+4,5+3,8+6,7\\\sf p=20\,cm\\\rm e)~\sf aqui\,basta\,somar\,as\,medidas\,e\,multiplicar\,por\,2.\\\sf p=(4+2)\cdot2\\\sf p=6\cdot2\\\sf p=12\,cm\\\rm f)~\sf p=5+4+3\\\sf p=12\,cm\\\rm g)~p=3+3+2\\\sf p=8\,cm\end{array}}$
