Question

ayuda HALLAR EL AREA SOMBREADA DE LAS SIGUIENTES FIGURAS​

Answer 1

Respuesta:

Explicación paso a paso:

$Para -el -rectangulo:$

$Base: b =10cm$

$Altura: h = \frac{6cm}{2} = 3cm$

$Area-sombreada: As=?$

$As = \frac{b*h}{2} = \frac{10cm*3cm}{2}$

$As = \frac{30cm^{2} }{2}$

$As = 15cm^{2}$

-------------------------------------------------------------------------------------------------------

$Para-el-cuadrado:$

$Area: A = 16 cm^{2}$

$Lado: L = ?$

$L = \sqrt{A}$

$L = \sqrt{16cm^{2} } = 4cm$

$Area-sombreada: As=?$

$As =Area-del -triangulo ABD -menos- Area-del-triangulo ABM$

$As = \frac{AB * AD}{2} -\frac{AD*AM}{2} = \frac{4cm* 4cm}{2} -\frac{4cm*2cm}{2}$

$As = \frac{16cm^{2} }{2} -\frac{8cm^{2} }{2} = 8cm^{2} -4cm^{2}$

$As = 4cm^{2}$

----------------------------------------------------------------------------------------------------------

$Para-el-paralelogramo:$

$Area: A = 64cm^{2}$

$Area-sombreada: As=?$

$As = 2 ( \frac{A}{4} ) = 2 ( \frac{64cm^{2} }{4} ) = \frac{128cm^{2} }{4}$

$As = 32cm^{2}$
