5) Con una cuerda de 34 metros se puede dibujar un rectángulo (sin que sobre cuerda) cuya diagonal mide 13 metros. Calcular cuánto mide el área de dicho rectángulo. \[ 13^{2}=(17-x)^{2}+x^{2} \rightarrow x^{2}-\square x+\square=0 \rightarrow(x-O)(x-\square)=0 \rightarrow x=0 \] Respuesta/ El área del rectángulo es de \( \square m^{2} \)
