Answer 2

Information provided with us:

• Length of a side of triangle is 6cm
• Second side is twice the third side
• Perimeter of the triangle is 18cm

Using the concept:

• Triangles

Formula of perimeter of triangle:

• Perimeter of triangle = Sum of its three sides

We know that:

• First side is of length 6cm

Let us assume:

• Length of third side be y

According to the question:

• Second side would be of length 2y

(As it was twice the third side)

Substituting the required values in formula:

Again given,

• First side = 6
• Second side = 2y
• Third side = y

Putting values,

➝ 6 + 2y + y = 18

➝ 6 + 3y = 18

Reversing the sides,

➝ 3y = 18 - 6

Now,

➝ 3y = 12

➝ y = 12/3

On dividing 12 with 3 we gets,

➝ y = 4

Therefore, y is 4cm.

Finding out sides of triangle:

→ First side = 6cm

→ Second side = 2y = 2 × 4 = 8cm

→ Third side = y = 4cm
