Question

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

Answer 1

let the sides be 12x,17x and 25x
so,
12x + 17x+25x =540
54x=540
x=540÷54
x=

Answer 2

Answer:

Step-by-step explanation:

12x+17x+25x=540

or 54x=540

or x=10

sides are 120, 170, 250

s= (120+170+250)= 270

area= √270(270-120)(270-170)(270-250)

      =√270Х150Х100Х20

     =√81000000

     =9000
