A rectangular window is twice as long as it is wide. If its perimeter is 14 feet, then what are its dimensions in feet?
Pick one
A) 3/2 by 7/2  B) 7/3 by 14/3  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 = 14   6x = 14   x = 14/6 = 7/3   The width is 7/3 and the length is 14/3.   The answer is 7/3 by 14/3.
