Answer 2

⇒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 cms

⇒2S=540

⇒S=270 cm

A= √ s(s−a)(s−b)(s−c) = √270(270−120)(270−170)(270−250) cm²

= 270×150×100×20cm²

A=9000 cm ²
