Wouldn't a fixed length of the diagonal fix the length and breadth?
For a square, yes, but for a rectangle, no, not at all. If you have a diagonal, say, of length 10, you might have sides of 6 and 8, or you might have sides of 5 and 5√3, or you might have a square with sides of 5√2 and 5√2, among many other possibilities.

Is the surface area of a rectangular carpet larger than 1000 square feet?
I assume this is just a badly-written question, and the solutions above are probably all correctly guessing its intended meaning. But "surface area" is a 3-dimensional concept. To find the "surface area" of this carpet, we'd need to add the areas of both sides of the carpet, along with any small area we get around the edges because of the carpet's height. I doubt that's what the question means -- it probably just means to ask about ordinary "area" -- but the answer is C no matter how you interpret it.
