Ratio of sides
12: 17:25
let them be
12x,17x, 25x respectively
perimeter of a triangle = sum of all sides
540 = 12x,17x, 25x
540 = 54x
x = 10
all sides measure
12x = 12×10 = 120
17x = 17× 10 = 170
25x= 25 × 10 = 250
it's semipetimeter = 540/2 = 270
using heron's formula area of the triangle =√ (s)(s-a)(s-b)(s-c)}
where s is the semipetimeter and a,b,c
area the sides of the triangle.
√ {( 270)(270-120)(270-170)(270-250)}
= 9000cm^2.
