Given :-
- ratio of sides of a triangle is 12:17:25
- perimeter of the triangle = 540 cm
To Find :-
- find the area of the triangle ?
Solution :-
let the sides of the triangle are 12x , 17x and 25x
and we know that,
so, the sides of the triangle are
- 12 × 10 = 120 cm
- 17 × 10 = 170 cm
- 25 × 10 = 250 cm
__________________________
now, find the area of the triangle by using heron's formula
if the sides of the triangle are a, b and c then,
where,
and here
- a = 120 cm
- b = 170 cm
- c = 250 cm
then,
now, area of the triangle
hence, area of the triangle is 9000 cm²
