Question

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

Answer 1

Let the number be $x$

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

$9x=54$

$x=54/9=6$

The sides of the triangle are

$2x=2\times 6=12$

$3x=3\times 6=18$

$4x=4\times 6=24$

Then,

We get the sides of the triangle are $12,18$ and $24$.
