### Hint:

In this question, we have to find the ratio of the perimeter of the triangle to the largest side of the triangle. As we know that the sum of angles of triangle is 180 degrees, so we can find the angles using the ratio. Now, let's assume the length of a=b=y so using the cosine formula we can find the value of c. And later find the ratio of the perimeter (i.e., a +b +c) to largest side (i.e., c).
