hope it helps you

Answer 2

hey buddy to find the answer of this question you have to apply herons formula

herons formula=√[s (s – a)(s – b)(s – c)]

where a, b and c are three sides of the triangle

s is the semi-perimeter.

Perimeter of the triangle=4+6+8=18cm

Hence semi-perimeter =18/2=9cm

then area of the triangle=√[9 (9 – 4)(9 – 6)(9 – 8)]

                                         =√[9 (5)(3)(1)]

                                         =3√15cm^2
