Answers 13-15 refer to the inequation (0 < a < 1 < b)

13. 0 < a < 1 implies that a² = a ´ a < a
    e.g. 5² = 0.5 ´ 0.5 = 0.25 < 0.5

    Hence A.

14. 1 < b implies that b² = b ´ b > b
    e.g. (1. 2) ² = 1.2 ´ 1.2 = 1.44 > 1.20

    Hence B.

15. (a + b) ² = a² + 2ab + b² > a² + b²

    
    Since a > 0 and b > 0

    Hence A.

16. Area of square garden is 40' ´ 40' = 1600 sq.feet.
    Area covered by four sprinklers
    
    Hence area not sprinkled is 1600 - 1256 = 344.
    Hence percentage not sprinkled
    

    Hence E.
