1. Answer:

   The sum of the lengths of any two sides in a triangle is always greater than the length of the third side in the triangle.

   ⇒ The differnce of the lengths of any two sides in a triangle is always lesser than the length of the third side in the triangle.

   ⇒ The difference between 4cm and 7cm is

   3cm and their sum is 11cm.

   ⇒ To ensure that the above mentioned rule is not violated, the possible length of the third side has got to be greater than 3cm and lesser than 11cm.

   ⇒ So from the given options 6cm is less than

   11cm and greater than 3cm

   ∴ The length of the third side of triangle is 6cm
