Answer 2

Given:-

• The sides of triangled are in the ratio 1:2:3.

• The perimeter of triangle is 30cm.

To Find:-

• The sides of Triangle.

Formulae used:-

• Perimeter of Triangle = a + b + c.

Here,

Let, The ratio be "x"

• a = x

• b = 2x

• c = 3x

Now,

→ a + b + c = 30

→ x + 2x + 3x = 30

→ 6x = 30

→ x = 30/6

→ x = 5

Hence, The Value of x is 5.

• a = x → 5

• b = 2x → 2 × 5 → 10

• c = 3x → 3 × 5 → 15

Therefore, The Sides of Triangle is 5,10 & 15 respectively.
