Answer:

Ancho: x

Largo: 2x + 4

PERÍMETRO DEL RECTÁNGULO:

P = 2(Largo) + 2(Ancho)

luego pasa por este:

32 = 2(2x + 4) + 2x

32 = 4x + 8 + 2x

32 = 6x + 8

32 - 8 = 6x

24 = 6x

24/6 = x

4 = x

Lo cambias por este:

Ancho: x = 4 pies

Largo: 2x + 4 pies = 2(4 pies) + 4 pies = 12 pies es de PERRITOS1000

Answer:

$\huge\boxed{x=\sqrt{70}}$

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

$\dfrac{AB}{AD}=\dfrac{AC}{AB}$

Substitute:

$AB=x\\AC=7+3=10\\AD=7$

$\dfrac{x}{7}=\dfrac{10}{x}$ cross multiply

$(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}$
