than what? Unless you specify some constraints,
this formulation is incorrect. There are scalene
triangles with areas greater than that of
some isosceles triangles of equal perimeter.
For the statement to be true you have to fix
the base. After you do, think of how you draw
an ellipse with two given foci.

Hope the above helps.
