However it is not necessary that if they are complementary angles they must share a side.Any angles that add up to 90 degree,can be considered complementary.
If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w) = 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w. So the answer is the last one.
