and sides are in ratio 25:17:12
So, the sides are 25x , 17x , 12x where x is any positive no.
then ,25x + 17x + 12x = 540
54x = 540
x = 10
25x = 25 * 10 = 250
17x = 17*10 = 170
12x = 12*10 = 120
So, the sides are 250m , 170m & 120m.
now, the semi - perimeter is S = 540/2 = 270 m
we know the Heron's formula:-
area of triangle =
where, a,b,c is the sides of triangle and s is the semi-perimeter.
now, the area of the triangle is
= m²
= m²
= m²
= m²
= 9000m²
Hence, the area of triangle = 9000m²
I HOPE ITS HELP YOU DEAR,
THANKS
