Given :
- Sides of the triangle : 56cm, 60cm and 52cm.
To Find:
- Area of the triangle.
Solution:
heron's formula :-
- a = area of the triangle.
- s = semi-perimeter
- a, b, c = sides of the triangle.
semi-perimeter of the triangle :
⟹ 1/2 × ( a + b + c)
⟹ 1/2 ( 56cm + 60cm + 52cm)
⟹ 1/2 ( 168cm)
⟹ 84cm
substitute the values :-
1344cm² is the area of the triangle
