Answer 2

Here we are given the three sides of the triangle.

So we have Heron's formula to find its area.

Heron's formula is given by :

`A=√(S(S-A)(S-B)(S-C))`

where A, B and C are sides of triangle and S is semi perimeter which is given by,

`S=(A+B+C)/(2)`

plugging values of A, B and C to find S

`S=(16+12+8)/(2)`

S=18

Now plugging values of A, B , C and S in Heron's formula

`A=√(S(S-A)(S-B)(S-C))`

`A=√(18(18-12)(18-8)(18-16))`

A=46.48 m²

Answer: Area of triangle is 46.48 m².
