Question

Find the perimeter of a triangle whose sides are 4x + 2y ; 3y-x ; x-3y

Answer 1

Given:

A triangle with

• 1st side = 4x + 2y
• 2nd side = 3y - x
• 3rd side = x - 3y

What To Find:

We have to find the perimeter of the triangle.

How To Find:

To find the perimeter of the triangle we will use,

• Perimeter = Sum of all sides
• Then substitute and solve.

Solution:

Using the formula,

⇒ Perimeter = Sum of all sides

Substitute the values,

⇒ Perimeter = (4x + 2y) + (3y - x) + (x - 3y)

Remove the brackets,

⇒ Perimeter = 4x + 2y + 3y - x + x - 3y

Rearrange the like terms,

⇒ Perimeter = 4x - x + x + 2y + 3y - 3y

Solve the first term,

⇒ Perimeter = 4x + 2y + 3y - 3y

Solve the second term,

⇒ Perimeter = 4x + 2y

∴ Thus, the perimeter of the triangle is 4x + 2y.
