Answer 1

Explanation:

perimeter=36

let the ratio be x

therefore,

⇒AB+BC+CA=36

⇒3x+4x+5x=36

⇒12x=36

⇒x=

12

36

⇒x=3

Now, putting the value of x

AB=3x=9cm

BC=4x=12cm

AC=5x=15cm

On using Pythagoras theorem

AC

=AB

2

+BC

=81+144

AC

=225

AC=15cm

ΔABC is right angled triangle ∠B is right angle.

Area of

ΔABC=
