- The formula for the perimeter of a rectangle is \(P = 2(L + B)\), where \(L\) is the length and \(B\) is the breadth.

- Given: Perimeter = 40 cm, Breadth = 8 cm.

- Substitute into the formula: \(40 = 2(L + 8)\).

- Simplify to find length: \(20 = L + 8\).

- Solve for \(L\): \(L = 20 - 8 = 12\).

- The length is 12 cm, and the breadth is 8 cm.

- The difference between the length and breadth: \(12 - 8 = 4\).

- Correct Answer: Option 2: 4 cm
