Question

find the area of triangle with sides are respectively 150 cm 120 cm and 200 CM

Answer 1

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
