Given:

Given that the lengths of to sides of a triangle are 7 am and 11 cm.

Required: Identify the length of the third side which is not possible.

Explanation:

Use the triangle inequality which states that the sum of any two sides of a triangle is greater than or equal to the third side, that is, the third side of a triangle must be equal or less than the sum of the other two sides.

Here, the sum of the two given sides i 7+ 11 = 18.

So, the third side cannot be greater than 18.

FromI the given options,19 > 18. Hence it cannot be the length o the third side of the triangle.

Final Answer: The length which could not be the measure of the third side is 19 cm.
