Answer 2

GivEn values:

• Side of traingle = 3x+1, 4x+2, 5x

To finD:

• Perimeter of triangle.

Solution:

We have given that three sides of triangle are 3x+1, 4x+2 and 5x respectively.

To find perimeter of this triangle, we will use a formula.

Formula using :

Perimeter of triangle = A + B + C

Where,

• A = first side of triangle = 3x +1 ••••( given)
• B = second side of triangle = 4x + 2 ••••( given)
• C = third side of triangle = 5x •••••( given)

Substituting values in formula:

Perimeter of triangle = A + B + C

=> Perimeter of triangle = (3x+1)+(4x+2)+(5x)

=> Perimeter of triangle = 3x + 4x + 5x + 1 +2

=> Perimeter of triangle = 12x + 3

$\large{\boxed{\tt{\pink{ ∴\: Perimeter\: of\: triangle\: is\: 12x +3}}}}$
