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 ?
"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 2 x ^ 2 . the area of the original square is 1 / 2 = 50 % times the area of the new square . the answer is c ."
