Explicación paso a paso:
a )
[tex]Base: b = 18dm[/tex]
[tex]Altura: h = 7dm[/tex]
[tex]Area: A = ?[/tex]
Fórmula:
[tex]A = \frac{Base* Altura}{2} =\frac{b*h}{2}[/tex]
[tex]A = \frac{18dm*7dm}{2} = \frac{126}{7} dm^{2}[/tex]
Respuesta:
[tex]A = 63dm^{2}[/tex]
________________________________________________________
b )
[tex]Base: b = 10cm[/tex]
[tex]Altura: h = 3cm[/tex]
[tex]Area: A = ?[/tex]
Fórmula:
[tex]A = \frac{Base* Altura}{2} = \frac{b*h}{2}[/tex]
[tex]A = \frac{10cm*3cm}{2} = \frac{30cm^{2} }{2}[/tex]
Respuesta:
[tex]A = 15cm^{2}[/tex]

c )
Base-mayor: B = 13m
[tex]Base-menor: b = 9cm[/tex]
[tex]Altura: h = 4m[/tex]
[tex]Area -del - trapecio: At = ?[/tex]
Fórmula:
[tex]At = \frac{(B+b)*h}{2}[/tex]
[tex]At = \frac{(13m+9m)*4m}{2} =\frac{(22m)*4m}{2} = \frac{88m^{2} }{2}[/tex]
Respuesta:
[tex]At = 44m^{2}[/tex]
