A rectangular window is twice as long as it is wide. If its perimeter is 20 feet, then what are its dimensions in feet?  Options
A) 3/2 by 7/2	B) 5/3 by 10/3	C) 2 by 4	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 = 20   6x = 20   x = 20/6 = 10/3   The width is 10/3 and the length is 20/3.   The answer is 10/3 by 20/3.
