Respuesta:
1) 60 cm2
2) 64.5 m2
3) 27 cm2
4) 110
5) 216.5
Explicación paso a paso:
1)
[tex]a = \frac{12 + 8}{2} \times 6 \\ a = \frac{20}{2} \times 6 \\ a = 10 \times 6 \\ a = 60 \: {cm}^{2} [/tex]
2)
[tex]p = 5 \times 6 \\ p = 30[/tex]
[tex]a = \frac{30 \times 4.3}{2} \\ a = \frac{129}{2} \\ a = 64.5 \: {m}^{2} [/tex]
3)
[tex]p = 4 \times 5 \\ p = 20 [/tex]
[tex]a = \frac{20 \times 2.7}{2} \\ a = \frac{54}{2} \\ a = 27 \: {cm}^{2} [/tex]
4)
[tex]p = 8 \times 5 \\ p = 40[/tex]
[tex]a = \frac{40 \times 5.5}{2} \\ a = \frac{220}{2} \\ a = 110[/tex]
5)
[tex]p = 10 \times 5 \\ p = 50[/tex]
[tex]a = \frac{50 \times 8.66}{2} \\ a = \frac{433}{2} \\ a = 216.5[/tex]
