Question

the sides of a triangle are in the ratio 25:17:12 and its perimeter is 540 metre find the area of the triangle ​

Answer 1

let the sides be 25x,17x,12x

A/Q

25X+17X+12X=540

54X=540

x=10

sides are= 25×10,17×10,12×10

250cm,170cm,120cm

semi perimeter=250+170+120/2

=540/2=270

area

$\sqrt{s(s - a)(s - b)(s - c)}$

270×20×100×150=81000000

$\sqrt{81000000}$

9000
