I hope it is useful for you yaar

Step-by-step explanation:

Given: the sides of a triangle are 3 cm, 5 cm and 4 cm.

To find out: Area of triangle

Solution:-

The lengths of the sides are a=3 cm, b=5 cm, c=4 cm.

∴s=

2

a+b+2

=

2

3+5+4

cm=6 cm

We use the formula,

Δ=

s(s−a)(s−b)(s−c)

.

∴Δ=

6(6−3)(6−5)(6−4)

cm

=

6×3×1×2

sq.cm

=6 sq.cm
