Answer 2

3) both statements put together are sufficient is the correct answer.

• The area of a rectangle is given by the formula: length*breadth. The perimeter of the rectangle is given by the formula: 2(length + breadth).
• Now, from the formula of the perimeter, the value of length and breadth can be calculated, as per the given relation.
• By knowing the length and breadth, the area of the rectangle can be easily calculated.
