GivEn:-
- The Perimeter of a triangle is 450 m.
- The ratio of sides of triangle are 13:12:15.
⠀⠀⠀⠀⠀⠀⠀
To find:-
- Area of triangle using Heron's formula.
⠀⠀⠀⠀⠀⠀⠀
Solution:-
⠀⠀⠀⠀⠀⠀⠀
☯ Let sides of triangle be 13x, 12x and 5x.
⠀⠀⠀⠀⠀⠀⠀
The Perimeter of a triangle is 450 m.
⠀⠀⠀⠀⠀⠀⠀
⠀⠀━━━━━━━━━━━━━━━━━━━━━
Therefore,
⠀⠀⠀⠀⠀⠀⠀
- a = 13x = 195 m
- b = 12x = 180 m
- c = 5x = 75 m
⠀⠀⠀⠀⠀⠀⠀
We know that,
