Question

If the sides of a triangle are in ratio 8: 15: 17 and its perimeter is 80 cm, then find its | area without using heron's formula.

Answer 1

Answer:

40 ---------- 80

1 ---------- 2

so, sides are = 16,30,34

Now,

(16)²+(30)² = (34)²

(256)+(900) = 1156

1156 = 1156

it means that ∆ is a right angled ∆

Area of ∆ = 1/2 * 16 * 30 = 240cm² (Ans)
