A rectangular window is twice as long as it is wide. If its perimeter is 12 feet, then what are its dimensions in feet? Choose the correct choice:	A) 2 by 4	B) 5/3 by 10/3	C) 2.5 by 5	D) 3 by 6	E) 10/3 by 20/3
Let x be the width of the window. Then the length is 2x.   x+2x+x+2x = 12   6x = 12   x = 2   The width is 2 and the length is 4.   The answer is 2 by 4.
