If the sides of a square are multiplied by 5, the area of the original square is how many times as large as the area of the resultant square? Pick one.
A) 4%  B) 25%  C) 50%  D) 200%  E) 400%
Let x be the original length of one side.   Then the original area is x^2.   The new square has sides of length 5x, so the area is 25x^2.   The area of the original square is 1/25 = 4% times the area of the new square.   The answer is 4%.
