Each of the line segments parallel to one side of the triangle, along with portions of the other two sides, forms a triangle that is similar to the whole triangle.

The triangle formed by the longest of those parallel line segments has an area 5/6 of the area of the original. That is, the ratio of the areas is 5:6.

In any two similar figures, if the ratio of the areas is A:B, then the ratio of similarity is sqrt(A):sqrt(B). So in this problem the ratio of similarity is sqrt(5):sqrt(6).

And so the length of the longest of the line segments parallel to the side with length 24 is

24%2A%28sqrt%285%29%2Fsqrt%286%29%29

Convert that to another form if required.
