(a) 5
(b) 8
(c) 10
(d) 12
Solutions:
S1. Ans.(b)
S2. Ans.(a)
S3. Ans.(b)
S4. Ans.(a)
S5. Ans.(c)
S7. Ans.(a)
Sol. Perimeter of semicircle = r (2 + ?)
36 = r (2 + 22/7)
r = 7m
S8. Ans.(d)
Sol. 3 4 5
area = 1/2 × 3 × 4
= 6
S9. Ans.(c)
Sol. Area of regular hexagon = 6 × area of small equilateral triangle
= 6 × √3/4 × (2)^2
= 6√3
