If the sides of a square are multiplied by sqrt(2), the area of the original square is how many times as large as the area of the resultant square? Select:  A) 2%  B) 4%  C) 50%  D) 100%  E) 200%
Let x be the original length of one side.   Then the original area is x^2.   The new square has sides of length sqrt(2)*x, so the area is 2x^2.   The area of the original square is 1/2 = 50% times the area of the new square.   The answer is 50%.
