Question

The sides of triangle are in 3:4:5
if its perimetre is 36 then the area
of triangle is what ?​

Answer 1

${\huge{\boxed{\boxed{Answer...!!!!}}}}$

Let the sides of triangle be ...3x , 4x , 5x.

It is given that

Perimeter of triangle = 36

3x + 4x + 5x = 36

12x = 36

x = 36/12

x = 3

So,

the sides of triangle are :

3x = 3×3 = 9

4x = 4×3 = 12

5x = 5×3 = 15

Hence ,,,,

Area of triangle = 1/2 × base × height

= 1/2 × 9× 12

= 9×6

= 54
