Question

Find the area of a triangle whose sides are 150 , 120, and 200 cm long​

Answer 1

We can solve it by Heron's formula:-

So semi perimeter will be,

⇒150+120+200

           2  

⇒235 cm

So,By herons's formula:-

√s(s-a)(s-b)(s-c)

where a=150 cm......b=120 cm......c=200 cm

 By implying values:-

⇒√235(235-150)(235-120)(235-200)

⇒√235×85×115×35

⇒√80399375

⇒8966.57 cm²

So the area is :- 8966.57cm²
