Question. 15

The perimeter of the triangle shown in Fig. 7.1 is

(A)

2x + y

(B)

x + 2y

(C)

x + y

(D)

2x – y

Detailed Answer with Explanation:

Perimeter means the total length around the triangle — we add all its sides.
From the figure, the three sides are: x, x, and y.
Write the sum:

( ext{Perimeter} = x + x + y)
Add like terms:

(x + x = 2x)
So, the perimeter becomes:

(2x + y)

Answer: Option A — (2x + y).
