Question

Determine o perímetro de cada figura.

Answer 1

some todos os cálculos e depois faz aquele que é mais difícil responda é 15

Answer 2

A)
 
44 / 2
 22 / 2
11 / 11
1          =>2².11

  99 / 3
 33 / 3
11 / 11
 1        =>3².11

$\sqrt{44}= \sqrt{2^2\cdot11}=\ \textgreater \ 2\sqrt{11}\\\\ \sqrt{99}= \sqrt{3^2\cdot11}=\ \textgreater \ 3\sqrt{11}\\\\\\ P=2l+2c\\P=(2\cdot2\sqrt{11})+(2\cdot 3\sqrt{11})\\P=4\sqrt{11}+6\sqrt{11}\\\\\boxed{\boxed{P=10\sqrt{11}\ cm }}$


B)
125 / 5
 25 / 5
 5 / 5
 1          =5².5

   80 / 2
  40 / 2
 20 / 2
10 / 2
5 / 5
1               =>2².2².5

$\sqrt{125}= \sqrt{5^2\cdot5}=\ \textgreater \ 5\sqrt{5}\\ \sqrt{80}=\sqrt{2^2\cdot2^2\cdot5}=4\sqrt{5}\\\\\\ P=l_1+l_2+l_3\\P=3\sqrt{5}+4\sqrt{5}+5\sqrt{5}\\\\\boxed{\boxed{P=12\sqrt{5}\ cm}}$
