side of a triangle are in the ratio of 12:17:25 and it's perimeter is 540cm. fine it's area
​

Answer 1

Answer:

$\large \green{Solution}$☟︎︎︎

⇒Let x be common ratio.

∴ Sides of triangle will be: 12x,17x and 25x.

⇒Perimeter =540 cm(given)

⇒12x+17x+25x=540 cm,

⇒54x=540 cm

⇒x=10 cm

⁂Sides of triangle: a=120,b=170,c=250 cm's.

⇒2S=540

⇒S=270 cm

A= (Divition form) s(s−a)(s−b)(s−c)

= (Divition form)270(270−120)(270−170)(270−250)cm2.

= 270×150×100×20 cm 2.

A=9000 cm square.

$\large \green{Therefore,}$

Area of the triangle is 9000cm square⬜.
