Verified answer

Resposta:

A)

     P = 33,14

     A = 65,90

B)

     P = 26,70

     A = 29,37

Explicação passo a passo:

A)

P=[tex]\sqrt{99} .2+\sqrt{44}.2[/tex] ≅ 9,94.2+6,63.2 = 19,88 + 13,26 = 33,14

A= [tex]\sqrt{99} .\sqrt{44}[/tex] ≅ 9,94.6,63 = 65,90

B)

P= [tex]\sqrt{125}+3\sqrt{5} +\sqrt{80}[/tex] ≅ 11,20+3.2,20+8,90 = 11,20+6,60+8,90 = 26,70

A= [tex]\sqrt{80} .3\sqrt{5}[/tex] : 2 ≅ 8,90.6,60 : 2 = 58,74 : 2 = 29,37
