Explanation:

Step1: Área del triángulo mayor

$\text{Área}_{\text{mayor}} = \frac{65 \times 80}{2} = 2600$

Step2: Área del triángulo menor

$\text{Área}_{\text{menor}} = \frac{39 \times 48}{2} = 936$

Step3: Área de la región sombreada

$\text{Área}_{\text{sombreada}} = 2600 - 936 = 1664$

Answer:

1664 square yards
