Respuesta:
[tex]Base: 20cm[/tex] ; [tex]Altura: 15cm[/tex]
Explicación paso a paso:
[tex]Base: b[/tex]
[tex]Altura: h = \frac{3}{4} b[/tex]
[tex]Perimetro:P = 70cm[/tex]
Fórmula:
P = 2 (Base) + 2 ( altura )
P = 2 b + 2 h
[tex]70cm = 2 ( b) + 2 ( \frac{3b}{4} )[/tex]
[tex]70cm = 2b + \frac{6b}{4}[/tex]
[tex]70cm = \frac{8b+6b}{4}[/tex]
[tex]4(70cm) = 14b[/tex]
[tex]280cm = 14b[/tex]
[tex]\frac{280cm}{14} = b[/tex]
[tex]20cm = b[/tex]
[tex]h = \frac{3}{4} (20cm) = \frac{60cm}{4} = 15cm[/tex]
RESPUESTA:
Base: b = 20 cm
Altura: h = 15 cm
