Question

The sides of a triangle are in the ratio of $12:17:25$ and its perimeter is $540cm.$ Find its sides.

Answer 1

Let the sides of the triangle be $12x,17x,25x$.

By using the fact that the perimeter of the given triangle is $540cm,$

$12x+17x+25x=540$

$\Rightarrow 54x=540$

$\Rightarrow x=10$

Then the sides of the triangle are $120cm,170cm$, and $250cm.$
