Question

Sides of a triangle are cm 45 cm ,39cm, and 42cm, find its area?

Answer 1

a=45cm

b=39cm

c=42cm

s=a+b+c/2s

s=45+39+42/2

s=63

area of triangle =

$\sqrt{63(63 - 45)(63 - 39)(63 - 42)}$

$\sqrt{63 \times 18 \times 24 \times 21}$

$\sqrt{7 \times 3 \times 3 \times 3 \times 2 \times 3 \times 3 \times 2 \times 2 \times 2 \times 3 \times 7}$

7*3*3*3*2*2

=756
