Answer 2

Answer:

Option C

Step-by-step explanation:

Given :-

sides of a traingle are in the ratio 2:1:3 its perimeter is 24 cm.

To Find :-

Length of longest side

Solution :-

Let, the sides be 2x,x and 3x

Perimeter of triangle = a + b + c

24 = 2x + x + 3x

24 = 6x

24/6 = x

4 = x

Longest side = 3x

3x

3(4)

12 cm

Option C is correct
