Question

If sides of a triangle are int he ratio of $12:17:25$ and its perimeter is $540cm$, then find itssides

Answer 1

Let the Side of a triangle be $12x$,$17x$ and $25x$ respectively.

Perimeter of the traingle$=540=12x+17x+25x$

$\Rightarrow 54x=540$

$\therefore x=\frac{540}{54}=10$cm

$\Rightarrow$ sides of the triangle are $12x=12\times 10=120$cm

$17x=17\times 10=170$cm and $25x=25\times 10=250$cm

$\therefore$ the sides are $120$cm,$170$cm and $250$cm.
