Question

Find the area of the triangle using Heron's formula i)30m,40m,50m​

Answer 1

Answer:

600 square meter

Step-by-step explanation:

area = root s(s-a)(s-b)(s-c)

Answer 2

Answer:

S = (a+b+c)/2

S = (30+40+50)/2

S = 120/2

S = 60

ar∆ = √s(s-a)(s-b)(s-c)

ar∆ = √60(60-30)60-40)(60-50)

ar∆ = √60(30×20×10)

ar∆ = √(60×6000)

ar∆ = √360000

ar∆ = 600cm^2
