Question

The sides of a triangle are in the ratio 2:3:4. If its perimeter is 54 cm, find the length
of the sides of the triangle ​

Answer 1

Let the sides be 2x, 3x & 4x

ATQ

we know,

Sum of sides of triangle = Perimter

2x + 3x + 4x = 54

9x = 54

x = 54/9

x = 6

Hence, sides are-

1. 2x = 2(6) = 12cm
2. 3x = 3(6) = 18cm
3. 4x = 4(6) = 24cm

Answer 2

Answer:

Let one side be 2x

Other be 3x

Another be 4x

so

$2x + 3x + 4x = 54 \\ 9x = 54 \\ x = 54 \div 9 \\ x = 6$

So one side is 2(6)=12

other be 3(6)=18

another be 4(6)=24

Step-by-step explanation:

so three sides are 12cm,18cm,24cm......
