Respuesta:
[tex]P = 24cm[/tex] ; [tex]D = 2\sqrt{26}cm[/tex] Ó [tex]10.198cm[/tex]
Explicación paso a paso:
[tex]Area: A =20cm^{2}[/tex]
[tex]Base: b =10cm[/tex]
[tex]Altura: h = ?[/tex]
[tex]Area : A = base * altura[/tex]
[tex]A =b*h[/tex]
[tex]20cm^{2} =10cm*h[/tex]
[tex]h = \frac{20cm^{2} }{10cm} = 2cm[/tex]
[tex]Perimetro: P = 2(base)+ 2 (altura)[/tex]
[tex]P = 2b+ 2h[/tex]
[tex]P = 2 (10cm )+ 2 ( 2cm ) = 20cm + 4cm[/tex]
[tex]P = 24cm[/tex]
[tex]Diagonal : D = ?[/tex]
Aplicando el teorema de Pitágoras:
[tex]D^{2} = b^{2} +h^{2}[/tex]
[tex]D^{2} = (10cm)^{2} + (2cm)^{2}[/tex]
[tex]D^{2} = 100cm^{2} +4cm^{2}[/tex]
[tex]D^{2} = 104cm^{2}[/tex]
[tex]D = \sqrt{104cm^{2} }[/tex]
[tex]D = \sqrt{4*26cm^{2}[/tex]
[tex]D = 2\sqrt{26} cm[/tex]
[tex]D =10.198cm[/tex]
