If the length of the side of a square is doubled, what is the ratio of the areas of the original square to the area of the new square?	Choose the correct choice from the following:
A) 1:4 B) 2:4 C) 3:4 D) 4:4 E) 5:4
Solution   If x be the side of the original square, then its area is equal to   x2   If x is doubled to 2x, then the new area is equal to   (2x)2 = 4 x2   The ratio of the areas of the original square to the area of the new square   x2 / (4 x2) = 1 / 4 or 1:4   1:4NSWER IS 1:4
