Step1: Calcular lado del mosaico pequeño
El lado horizontal del cuadrado grande es 1 unidad, dividido en 10 partes iguales.
Longitud horizontal: $\frac{1}{10}$ unidades
El lado vertical del cuadrado grande es 1 unidad, dividido en 7 partes iguales.
Longitud vertical: $\frac{1}{7}$ unidades
Step2: Calcular área del mosaico pequeño
El área de un rectángulo es base × altura.
$$\text{Área} = \frac{1}{10} \times \frac{1}{7} = \frac{1}{70}$$
Step3: Calcular área del rectángulo sombreado
El rectángulo sombreado tiene 5 mosaicos de ancho y 3 de alto, es decir $5 \times 3 = 15$ mosaicos.
$$\text{Área} = 15 \times \frac{1}{70} = \frac{15}{70} = \frac{3}{14}$$
