Question

19. The sides of triangle are 4x + 3y ,7x-2y
and 14x - 5y. Find its perimeter.
*​

Answer 1

Answer:

25x - 4y

Step-by-step explanation:

Perimeter of any object is the sum of all sides.

So, here, perimeter is:

⇒ (4x + 3y) + (7x - 2y) + (14x - 5y)

⇒ 4x + 3y + 7x - 2y + 14x - 5y

       Combine like terms:

⇒ 4x + 7x + 14x + 3y - 2y - 5y

⇒ 25x - 4y

     Perimeter is 25x - 4y
