Answer

La longitud del tercer lado de un triángulo debe ser menor que la suma de las longitudes de los otros dos lados y mayor que la diferencia absoluta de las longitudes de los otros dos lados.<br /><br />* **Límite superior:** 6.74 cm + 12.25 cm = 18.99 cm<br />* **Límite inferior:** |12.25 cm - 6.74 cm| = 5.51 cm<br /><br />Por lo tanto, la longitud del tercer lado debe estar entre 5.51 cm y 18.99 cm. Es decir, 5.51 cm < tercer lado < 18.99 cm.<br />
