Answer 1

✤ Question :-

Sides of the triangle are in ratio of 12 : 17 :25 and its perimeter is 540 cm find its area.

✤ Solution :-

Let the sides of triangle be = 12x , 17x , 25x

Perimeter of triangle = 540cm

A.T.Q.

12x+17x+25x = 540

54x = 540

x = 540/54

$\large{\green{\underline{\red{x\: =\:10\:cm}}}}$

Now, substituting the value of 'x'

$\large{\pink{\bigstar{\purple{\boxed{\red{12x\:=\:12*10=\:120\:cm}}}}}}$

$\large{\pink{\bigstar{\purple{\boxed{\red{17x\:=\:17*10=\:170\:cm}}}}}}$

$\large{\pink{\bigstar{\purple{\boxed{\red{25x\:=\:25*10=\:250\:cm}}}}}}$
