  15. The area of a plot is to be determined using Simpson's rule. The following offsets were taken to a boundary from points along a chain line all measurements being in metres 12, 15, 22, 29, 36, 38, 31, 22, 17.There were taken at 100 m intervals.
    Consider the following steps in this regard.
    1.
    2. Sum of the odd ordinates = 22 + 36 + 1 = 89
    3. Sum of the even ordinates = 15 + 29 + 38 + 22 = 104
    4. 12 + 17 = 39
    5. Area = 100 (19.5 + 89 + 104)
    6. Area = (39 + 2 x 89 + 4 x 104)
    7. Area 100 x 19.5 (104 - 89)
    The area of the plot can be determined by using the steps listed above :

  16. A.
    1, 2, 3 and 5
    B.
    1, 3, 4 and 6
    C.
    1, 2, 4 and 7
    D.
    2, 3, 4 and 6

  18. A.
    2 cm
    B.
    4 cm
    C.
    6 cm
    D.
    8 cm

  19. A buttress in a wall is intended to provide

  20. A.
    lateral support to roof slab only
    B.
    lateral support to wall
    C.
