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

Answer 1

Answer:

semiperimeter of triangle (s)=a+b+c whole by 2

area of triangle=√s(s-a)(s-b)(s-c)

where

s=semiperimeter

a;b;c are sides

s=150+120+200/2=470/2=235

area of triangle=√235(235-150)(235-120)(235-200)

=√235(85)(115)(35)=√80399375
