A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
                               y  = kx
Substituting the given values in the ordered pair,
                           5 = k(4)   ; k = 5/4

Answer:
<u><em>4 boxes of tiles.</em></u>
Step-by-step explanation:
Both rooms are square, so each has equal sides.  Let's set a side to room A as x.  It's area would be x^2.  Room B has sides = 2x, so it's area would be (2x)^2 or 4x^2.  The ratio of the areas B/A = 4x^2/x^2.  B/A = 4. 
Room B has 4 times the area of A.  If one box of tile completes Room A, Room B would need four times that amount, or 4 boxes.
