Nothing here makes sense.
-- The question talks about "Figure ABCS", but the picture is ABCD .
Where is 'S' ?
OK. Let's assume that it's really talking about Figure ABCD. Then
the whole problem is loaded with nonsense and red herrings.
-- When a figure is rotated, translated, or both rotated AND translated,
why should the length of any of its sides change ? You can just as well
forget all about the rotation, and just check out the length of the sides
as they sit in the drawing.
-- The third choice is there just to see who has a clue and who has none.
What in the world is "DD" ? It may apply to an article of women's clothing,
but it certainly has no relevance to this drawing. The distance from 'D' to
'D' is zero.
-- The side BC is 1 unit wide and 3 units high.
Its length is √(1+ 9) = √√10 .
So the first choice is not true.
-- The side CD is 4 unit wide and 1 unit high.
Its length is √(16 + 1) = √17.
<u><em>The second choice is true.</em></u>
But wait ! Don't go away.
-- As we've said, "DD" is a zero distance.
So the third choice is nonsense.
-- Side AB is 4 units wide and 1 unit high.
Its length is √(16 + 1) = √17 .
<em><u>The fourth choice is also true.</u></em>

Step-by-step explanation:
Given
4x + 3x ← x is common to both terms and can be taken out as a common factor, that is
4x + 3x = (4 + 3)x = 7x
