Step 1: Concept/Theorem

Triangle Inequality Theorem. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Step 2: Data given

Length of two sides 4 and 7.

Step 3

The third length must be less than the sum of the two length.

$4\text{ + 7 < 11}$

So 11 cannot be the length of the third side.
