Correct Answer
Option C
Explanation
To determine the least and greatest possible values of the perimeter \( P \) of a triangle with sides 5 cm and 10 cm, we need to consider the properties of triangles, specifically the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Let's denote the third side of the…Read More
