Answer 2

Largest side is 30 cm

Step-by-step explanation:

Ratio of the sides of a triangle are 13 : 14 : 15

Let the sides be 13x, 14x and 15x.

Perimeter of the triangle = 84 cm

13x + 14x + 15x = 84

42x = 84

$x=\frac{84}{42}$

x = 2

Sides of the triangle are

13x = 13 × 2 = 26 cm

14x = 14 × 2 = 28 cm

15x = 15 × 2 = 30 cm

Largest side is 30 cm.
