Question

The sides of a triangleare in the ratio12:14:25 and its perimeteris 25.5 cm. The largest side of a triangle is​

Answer 1

Step-by-step explanation:

Let the sides of the triangle be 12x cm , 14x cm and 25x cm

Thus, we have Perimeter = 12x +14x + 25x

25.5 = 51x

x = 25.5/51 = 0.5

Greatest side of the triangle = 25x = 25 x 0.5 = 12.5

Hope it will help you

Answer 2

Step-by-step explanation:

Solution :

Let the ratio be 12x, 14x, 25x.

Perimeter = 25.5 cm

12x + 14x + 25x = 25.5 cm

51x = 25.5

x = 25.5/51

x = 0.5

So,

12x = 12 × 0.5 = 6.0 cm or 6 cm

14x = 14 × 0.5 = 7.0 cm or 7 cm

25x = 25 × 0.5 = 12.5 cm

a = 6cm

b = 7cm

c = 12.5cm

Hence :

The largest triangle side is 12.5 cm.
