Question

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

Answer 1

let the number be x
2x+3x+4x=54
=>9x=54
=>x=54/9
=>x=6
the sides of the triangle are
2x=2×6=12
3x=3×6=18
4x=4×6=24

the sides of the triangle are 12 18 and 24

Answer 2

Answer:

The sides of the triangle are 12, 18 and 24.

Step-by-step explanation:

Given : The sides of a triangle are in the ratio 2 : 3 :4. If the if its perimeter is 54 cm.

To find : Its length of sides of the triangle ?

Solution :

Let the number be 'x'.

So, sides of triangle is 2x,3x and 4x.

The perimeter is sum of sides of triangle.

$2x+3x+4x=54$

$9x=54$

$x=\frac{54}{9}$

$x=6$

The sides of the triangle are

$2x=2\times 6=12$

$3x=3\times 6=18$

$4x=4\times 6=24$

The sides of the triangle are 12, 18 and 24.
