2(x+6) + 2(x) =40
2x +12+2x=40
4x+12=40
4x=28
x=7
Now to find area it is LxW

7x13=91

So the area of the rectangle is 91 meters squared

zhannawk [14.2K]

Answer:

15.26km

Step-by-step explanation:

Con la informacion de la pregunta e hecho un diagrama de la situacion. Podemos ver en el diagrama que el recorido forma un triángulo rectángulo. Entonces para saber la distancia que recorreria por el camino recto desde su casa a su trabajo tendriamos que calcular el valor de x, que se puede calcular usando el teorema de pitagoras que es el siguiente.

a^{2} + b^{2} = c^{2}

donde a y b son el ancho y el alto del triangulo y el c seria x

8^{2} + 13^{2}  = x^{2}

64 + 169 = x^{2}

233 = x^{2}

15.26 = x

Finalmente, podemos ver que la distancia seria 15.26km
