Question

If a perimeter of a triangle is x cm and its sides are p, q, r cm. what will be the area of triangle. Use herons formula​

Answer 1

Answer:

√(x/2)(x/2 - p)(x/2 - q)(x/2 - r)

Step-by-step explanation:

Heron's Formula = √(s)(s-a)(s-b)(s-c)

Here,

a = p cm

b = q cm

c = r cm

s = (p + q + r) ÷ 2 = x ÷ 2 = x/2

So, by using Heron's Formula,

√(x/2)(x/2 - p)(x/2 - q)(x/2 - r)
