Question

side of traingle in ratio 12:17:15and perimeter 540 find area

Answer 1

let sides of triangle =12y,17y,15y
perimeter =540
12y+17y+15y=540
44y=540
y=540/44
y= find this with your calculator
Hope you find this helpful

Answer 2

your question has a mistake it is 25 not 15

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

perimeter = 540

12x + 17x + 25x = 540

54x = 540

x = 540/54

x = 10

a = 12x = 12 x 10 = 120

b = 17x = 17 x 10 = 170

c = 25x = 25 x 10 = 250

s = a/2 + b/2 + c/2 = 540/2 = 270

area = √ s ( s-a ) ( s-b ) ( s-c )

simplify the values and the ans is 9000 cm²
