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 :

[tex] A=\sqrt{S(S-A)(S-B)(S-C)} [/tex]

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

[tex] S=\frac{A+B+C}{2} [/tex]

plugging values of A, B and C to find S

[tex] S=\frac{16+12+8}{2} [/tex]

S=18

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

[tex] A=\sqrt{S(S-A)(S-B)(S-C)} [/tex]

[tex] A=\sqrt{18(18-12)(18-8)(18-16)} [/tex]

A=46.48 m²

Answer: Area of triangle is 46.48 m².
