Answer:

Let one side of triangle=2x cm

and second side of triangle=7x cm

and third side of triangle=11x cm

We know that sum of triangle is 180°

So,2x+7x+11x=180°

20x=180°

x=180/20

x=9cm

So,one side of triangle=2x→2×9=18cm

second side of triangle=7x→7×9=63cm

third side of triangle=11x→11×9=99cm

Hope it helps
