Question

Área formula de heron... Ayuda! ​

Answer 1

Respuesta:

Explicación paso a paso:

$a = 36cm$

$b = 36cm$

$c = 28cm$

$Semi-perimetro: P = ?$

$Area: A = ?$

Fórmula de Herón:

$A = \sqrt{p(p-a)(p-b)(p-c)}$

$Semi-perimetro: P = \frac{a+b+c}{2} = \frac{36cm+36cm+28cm}{2}$

$P = \frac{100cm}{2} = 50cm$

Reemplazando.

$A = \sqrt{50cm(50cm-36cm)(50cm-36cm)(50cm-28cm)}$

$A = \sqrt{50cm(14cm)(14cm)(22cm)}$

$A = \sqrt{215600cm^{4} }$

$A = 464.33cm^{2}$

RESPUESTA:

    $464.33cm^{2}$
