Explanation:

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.
$$\text{Área} = 15 \times \frac{1}{70} = \frac{15}{70} = \frac{3}{14}$$

Answer:

  1. Each small tile has side lengths $\frac{1}{10}$ units and $\frac{1}{7}$ units.
  2. The area of each small tile is $\frac{1}{70}$ square units.
  3. The area of the shaded rectangle is $\frac{3}{14}$ square units.
