To answer this question, you need to understand the concept of perimeter and how it is calculated for a rectangle.

The perimeter of a rectangle is the sum of all its side lengths. A rectangle has two pairs of equal sides, so we can represent its side lengths as L (length) and B (breadth).

Let's go through each option to understand why it is correct or incorrect:

Option A) LxB - This option is incorrect. It represents the area of the rectangle, not its perimeter.

Option B) 2x(L+B) - This option is correct. It represents the sum of the two lengths and two breadths, which gives us the total perimeter of the rectangle.

Option C) 2x(LxB) - This option is incorrect. It represents twice the area of the rectangle, not its perimeter.

Option D) (LxB)^2 - This option is incorrect. It represents the square of the area of the rectangle, not its perimeter.

The correct answer is Option B) 2x(L+B). This option is correct because it represents the sum of all the side lengths of a rectangle, which gives us its perimeter.
