1. Answer:

   12 cm

   Step-by-step explanation:

   Given: ABC is a right triangle in which, AB = 13 cm & AC = 5 cm

   Solution:

   We know that in a right–angled triangle,

   h² = b² + p²

   A/Q, h = 13 cm & p = 5 cm

   h² = b² + p²

   => 13² = b² + 5²

   => b² = 169 – 25

   => b² = 144

   => b = root 144

   b = 12 cm

   Therefore, the length of BC = b = 12 cm.
