Question

Hola, alguien podría sacar el área de esta figura porfavorrr es urgenteeee ･ᴗ･​

Answer 1

Respuesta:

     $At = 18x^{2} +13x+1$

Explicación paso a paso:

$Area: At = ?$

$At = [ ( 5x- 1 )- (x-2 ) ] * [ (4x+3)] +[ (x+1 ) * ( x-2 )] +[ ( x) * ( x-2 ) ]$

$At = (5x-1-x+2)*(4x+3)+ ( x+1)*(x-2)+ (x)*(x-2)$

$At = (4x+1)*(4x+3)+ (x-2)(x+1+x) = ( 4x+1)*(4x+3)+(x-2)*(2x+1)$

$At = 4x(4x +3 ) + 1 (4x+3 ) + x ( 2x+1 ) -2 ( 2x+1 )$

$At = 16x^{2} +12x + 4x+3 + 2x^{2} +x -4x -2$

$At = 18x^{2} +13x+1$
