# Find the Area of a Triangle Whose Sides Are Respectively 150 Cm, 120 Cm and 200 Cm ? - Mathematics

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

#### Solution

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
