Question

Three sides of a triangle are x cm, y cm and 2x cm. Find the perimeter of the triangle​

Answer 1

Answer :-

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

Step-by-step explanation:

To Find :-

• The perimeter of triangle

Solution:

Given that,

The three sides of triangle are :-

• ( x ) cm
• ( y ) cm
• ( 2x ) cm

We know that,

Perimeter of triangle = Sum of three sides,

Therefore,

• The perimeter of triangle is :-

⟶ Perimeter = ( x )cm + ( y )cm + ( 2x )cm

⟶ Perimeter = [ x + y + 2x ] cm

⟶ Perimeter = [ x + 2x + y ] cm

⟶ Perimeter = ( 3x + y )cm

Hence, The perimeter of ∆ is (3x+y)cm.

Answer 2

Answer:

Given :-

• Three sides of a triangle are x cm , y cm and 2x cm.

To Find :-

• What is the perimeter of a triangle.

Formula Used :-

➲ Perimeter of a triangle = Sum of all sides of a triangle.

Solution :-

Given :

• First side (a) = x cm
• Second side (b) = y cm
• Third side (c) = 2x cm

According to the question by using the formula we get,

↦ Perimeter of a triangle = a + b + c

↦ Perimeter of a triangle = x + y + 2x

↦ Perimeter of a triangle = x + 2x + y

↦ Perimeter of a triangle = 3x + y

➠ Perimeter of a triangle = 3x + y cm

∴ The perimeter of a triangle is 3x + y cm .
