(A)

2x + y

(B)

x + 2y

(C)

x + y

(D)

2x – y

Detailed Answer with Explanation:

  1. Perimeter means the total length around the triangle — we add all its sides.

  2. From the figure, the three sides are: x, x, and y.

  3. Write the sum:

    ( ext{Perimeter} = x + x + y)

  4. Add like terms:

    (x + x = 2x)

  5. So, the perimeter becomes:

    (2x + y)

Answer: Option A — (2x + y).
