7. Which of the following option is correct if a,b and c are the areas of the given figures (i), (ii) and (iii) respectively? (π = 22/7)

a) a < b < c
b) a > b > c
c) a < b > c
d) b < c > a
View Answer

Answer: a
Explanation: Area of triangle = \(\frac{1}{2}\) × b × h = \(\frac{1}{2}\) × 2 × 5 = 5cm2
Area of rectangle = l × b = 5 × 2 = 10cm2
Area of circle = π(r)2 = \(\frac{22}{7}\) (7)2 = 154cm2.

9. Find the area of the Lawn.

a) 500m2
b) 101m2
c) 505m2
d) 504m2
View Answer

Answer: c
Explanation: Area of lawn can be found by subtracting the area of inner rectangle from square.
Hence, Area of lawn = Area of square – Area of rectangle = (25)2 – (15)(8) = 505m2.

10. Calculate the area of the given figure.

a) 14.28cm2
b) 12.28cm2
c) 7.14cm2
