Explicación paso a paso:
[tex]Ancho: a = 15cm[/tex]
El otro Lado, [tex]Largo: L = ?[/tex]
[tex]Perimetro: P = 82cm[/tex]
[tex]Area: A = ?[/tex]
Fórmula(s):
[tex]P= 2L +2a[/tex]
[tex]82cm = 2L + 2(15cm)[/tex]
[tex]82cm = 2L + 30cm[/tex]
[tex]82cm -30cm = 2L[/tex]
[tex]52cm = 2L[/tex]
[tex]\frac{52cm}{2} = L[/tex]
[tex]L = 26cm[/tex]
[tex]A= L * a[/tex]
[tex]A = 26cm* 15cm[/tex]
[tex]A= 390cm^{2}[/tex]
RESPUESTA:
[tex]Area(A) : 390cm^{2}[/tex]
