Question

tem jeito de me ajudar calcular essa duas questoes?

Answer 1

a)

$A=b*h\\A=\sqrt{3}*(1+\sqrt{2})\\A=\sqrt{3}*1+\sqrt{3}*\sqrt{2}\\A=\sqrt{3}+\sqrt{6}$

$2P=\sqrt{3}+\sqrt{3}+1+\sqrt{2}+1+\sqrt{2}\\2P=2\sqrt{3}+2+2\sqrt{2}\\2P=2(1+\sqrt{3}+\sqrt{2})$

b)

$A=(B+b)*h/2\\A=(3\sqrt{2}+2\sqrt{2})*\sqrt{2}/2\\A=5\sqrt{2}*\sqrt{2}/2\\A=5*2/2\\A=5$

$2P=1,5+1,5+2\sqrt{2}+3\sqrt{2}\\2P=3+5\sqrt{2}$
