Question

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

Answer 1

The triangle whose sides are
a = 150 cm
b = 120 cm
c = 200 cm
The area of a triangle =`sqrt(s(s-a)(s-b)(s-c)`

Here 1s = semi perimeter of triangle

`2s=a=b=c`

`s=(a+b+c)/2= (150+200+120)/2 =235 cm`

area of triangle =`sqrt(s(s-a)(s-b)(s-c)`

`=sqrt(235(235-150)(235-200)(235-120))`

`=sqrt(235(85)(35)(115))cm^2`

`=8966.56cm^2`
