Question

The side of triangle are the ratio 4: 5: 6. The permeter of the trianglesis45cm. Find the side of the triangle ​

Answer 1

Let the side of the triangle be 4x, 5x, 6x

Perimeter of Triangle = sum of all sides

45 = 4x + 5x + 6x

45 = 15x

x = 45/15

x = 3

Therefore, the side are 4x = 12cm

5x = 15cm

6x = 18cm

Answer 2

Answer:

let the sides of triangle

of triangle ABC

AB 4xcm

BC 5xcm

Ac 6xcm

now,as we know

perimeter(tri.)=sum of all sides

so, 4x+5x+6x=45cm

15x=45

x=45/15

x=3

now 4x=4×3=12cm

5×=5×3=15cm

6×=6×3=18cm.
