    b) 10 < A ≤ 10.5
    c) 10.5 < A ≤ 11
    d) 11 < A ≤ 11.5
    e) A > 11.5

  • Q23) Two of the vertices of the regular pentagon drawn on the co-ordinate plane are known to be (10,20) and (17,40). What is the ratio of the maximum possible area to the minimum possible area of such a pentagon?
    (Cos 36 = (√5 + 1)/4)
    a. 4 - (√5/2)
    b. 2 + (√5/2)
    c. (3 +√5)/2
    d. 3 + (2/√5)

  • Q24) Let VK and KJ be perpendicular line segments, each of which of length 6 cm. Suppose P and Q are the mid-points of VK and KJ respectively. If R is the point of intersection of VQ and PJ, then the area of triangle RQJ is

  • Q26) Mandakini draws a square ABCD of side 1 unit. She then draws 10 straight lines connecting A to each of 11 equally spaced points lying internally on CD (including C and D). What is the total area (in unit square) of all the possible triangles that can be formed
