**(a) b×h, this is the area of parallelogram. **

** **

**Question 2:**

** Find the area of quadrilateral ABCD. **

**(a) 11 **

**(b) 10 **

**(c) 9 **

**(d) 12 **

**Ans: **

**d = 4.5cm, h _{1} = 1.5 cm **

**h _{2} = 2.5cm, Area = ½ d (h_{1} + h_{2}) **

**= 1/2 × 4.5 × (2.5 + 1.5) cm ^{2} **

**= ½ × 4.5 × 4 cm ^{2} = 9 cm^{2} (c) **

** **

**Question 3: **

**Find the area of rhombus whose diagonals area of lengths 8cm and 6cm. **

**(a) 20 **

**(b) 24 **

**(c) 22 **

**(d) 21 **

**Ans: **

**Area of the rhombus = ½ d _{1} d_{2} **

**= 1/2 × 8 × 6cm ^{2} = 24 cm^{2} (b) **

** **

**Question 4: **

**The area of a rhombus 200 cm ^{2} and one of the diagonals is 20cm find the other diagonals **

**(a) 10 **

**(b) 12 **

**(c) 14 **

**(d) 8 **

**Ans: **

**Area of rhombus = 1/2 d _{1} d_{2} **

**200 cm ^{2} = 1/2 × 20 × d^{2} **

**200×2/20 = d _{2} **

**d _{2} = 10 cm (a) **

** **

**Question 5: **

**In a tower three are 20 cylindrical pillars. The radius of each pillar is 25cm and height is 8cm. Find the total cost of painting the curved surface area of all pillars at the rate of ****₹10 per m ^{2}? **

**(a) 2512 **

**(b) 2514 **

**(c) 2500 **

**(d) 2832 **

**Ans: **

**Radius of cylinder pillar = 25cm = 0.25cm **

**Curved surface are of a pillar = 2****rn **

**= 2 ****× 22/7 × 2.05 × 8 = 12.57 **

**Curved surface area of 20 such pillar **

**cost of painting = 12.57 × 2**

**= 251.4 **

**=10 × 251.4 **

**= 2514****₹ (b) **

** **

**Question 6: **

**Find the height of a cylinder whose radius 9cm and the total surface area is 564 cm ^{2} **

**(a) **

**(b) **

**(c) **

**(d) **

**Ans: **

**Total surface area = 2****r (h+r) **

**= 2 ****× 22/7 × 9 × (9 + h) **

**564 cm ^{2} = 396/7 (9 + h) **

**3948/396 = 9 + h **

**9.9696 = h **

**h = 0.9696 cm **

** **

**Question 7: **

**Find the side of the cube whose surface area is 2400 cm ^{2}? **

**(a) 20 **

**(b) 22 **

**(c) 24 **

**(d) 28 **

**Ans: **

**Surface area of the cube is = 2400/6 = a ^{2} **

**a = 20 **

**Question 8: **

**A closed cylindrical box of radius 14m and height 2m is made from a sheet of metal. How much sheet of metal required? **

**(a) 198 **

**(b) 178 **

**(c) 156 **

**(d) 176 **

**Ans: **

**Area of closed cylindrical box **

**= 2****rh **

**= 2 ****× 22/7 × 14m × 2m **

**= 2 × 22 × 2 × 2 **

**= 176m ^{2} (d) **

** **

**Question 9: **

**Find the volume of cylinder if the area of base is 14m and the height is 9m? **

**(a) 126 **

**(b) 144 **

**(c) 169 **

**(d) 225 **

**Ans: **

**Volume of cylinder = Area of base × height**

**= 14m ^{2} × 9m = 126 m^{3} (a) **

** **

**Question 10: **

**If the area of base is 225 m ^{3} and the volume of cuboid is 675 m^{3} then final the height? **

**(a) 4 **

**(b) 3 **

**(c) 9 **

**(d) 6 **

**Ans: **

**Volume of cuboid = Base area × Height **

**675m ^{3} = 225m^{3} × h **

**h = 3m (b) **

** **

**Question 11: **

**A Hall in the form of cuboid measures 40m, 20m, 10m. How many cuboi dal boxes can be stored in it in the volume of box is 2m ^{3} **

**(a) 6000 **

**(b) 4000 **

**(c) 2000 **

**(d) 1500 **

**Ans: **

**Volume of Hall = 40×20×10 = 8000m ^{3} **

**Numbers of boxes that can be stored in the hall = Volume of hall/volume of one box **

**= 8000 m ^{3}/2m^{3} = 4000 (b) **

** **

**Question 12: **

**Find the surface area of cube if the length of the side is 12cm **

**(a) 896 **

**(b) 849 **

**(c) 864 **

**(d) 894 **

**Ans: **

**Surface area of cube = 6l ^{2} **

**= 6×12 ^{2} **

**= 6×144 **

**= 864 cm ^{2} (c) 864 **

** **

**Question 13: **

**A water tank is in the form of cylinder whose radius 20cm and height/length is 60m. Find the quantity of water can be stored in the tank? **

**(a) 571.48 **

**(b) 75,428.5 **

**(c) 75,226 **

**(d) 75896 **

**Ans:**

**Volume of cylinder = ****r ^{2}h **

**= 22/7 ****× (20m) ^{2} × 60m **

**= 22×400×60/7 = 75,428.5 m ^{3} **

** **
