Answer 1

Answer:

area of triangle

by heron's formula,

√s(s-a)(s-b)(s-c)

s= 6 cm

√6x3x2x1

ans is 6 cm sq.

Step-by-step explanation:

Answer 2

A=3cm
B=4cm
C=5cm
semi perimeter=A+B+C/2
$area \: of \: triangle = \sqrt{s(s - a)(s - b)(s - c)}$
semi perimeter =3+4+5/2
=6
$\sqrt{6(6 - 3)(6 - 4)(6 - 5)}$
=6
