Question

Three sides of a triangle is x cm, ycm and 2x cm. find the perimeter of the triangle​

Answer 1

Answer:

• The perimeter of triangle is (3x + y) cm.

Step-by-step explanation:

Given that:

Sides of a triangle.

1. First side = x cm
2. Second side = y cm
3. Third side = 2x cm

To Find:

• The perimeter of the triangle.

Formula used:

• Perimeter of a triangle = Sum of of all the three sides

Finding the perimeter of triangle:

⇒ Perimeter = x + y + 2x

⇒ Perimeter = x + 2x + y

⇒ Perimeter = 3x + y

∴ Perimeter of triangle = (3x + y) cm

$\colorbox{skyblue}{Formula :}$

$\colorbox{pink}{Perimeter of a Δ = Sum of of all the three sides}$

Lets find the perimeter of Δ:

➻ Perimeter = x + y + 2x

➻ Perimeter = x + 2x + y

➻ Perimeter = 3x + y

$\colorbox{skyblue}{∴ Perimeter of Δ = (3x + y) cm}$
