- A.156
- B.176Correct
- C.196
- D.186
- E.166
Show solution
Circumference = 2πr = 2 × 22/7 × 28 = 176 cm.

- A.142
- B.192Correct
- C.242
- D.262
- E.122
Show solution
Area = length × breadth = 16 × 12 = 192 square cm.

- A.4225
- B.3475
- C.3850Correct
- D.4725
- E.2975
Show solution
Area = πr² = 22/7 × 35² = 3850 square cm.

- A.60 sq mCorrect
- B.34 sq m
- C.17 sq m
- D.120 sq m
Show solution
Area of a rectangle = length × breadth = 12 × 5 = 60 square metres.
- Question 5Easy
Find the perimeter of a square with side 9 cm.
- A.36 cmCorrect
- B.81 cm
- C.18 cm
- D.27 cm
Show solution
Perimeter of a square = 4 × side = 4 × 9 = 36 cm.
- Question 6Easy
Find the area of a triangle with base 12 cm and height 8 cm.
- A.48Correct
- B.58
- C.38
- D.32
- E.64
Show solution
Area = ½ × base × height = ½ × 12 × 8 = 48 square cm.
- Question 7Easy
Find the area of a circle of radius 7 cm (take π = 22/7).
- A.154Correct
- B.144
- C.164
- D.150
Show solution
Area = πr² = 22/7 × 7 × 7 = 154 cm².
- Question 8Easy
A rectangle is 12 cm by 10 cm. Find its area in square cm.
- A.120Correct
- B.125
- C.115
- D.105
- E.135
Show solution
Area = length × breadth = 12 × 10 = 120 square cm.
- Question 9Easy
The area of a rectangle is 240 square cm and its length is 20 cm. What is its breadth in cm?
- A.10
- B.11
- C.12Correct
- D.14
- E.15
Show solution
Area equals length times breadth, so breadth is area divided by length: 240 / 20 = 12 cm.
- Question 10Easy
The perimeter of a square is 56 cm. What is its area in square centimetres?
- A.169
- B.182
- C.196Correct
- D.210
- E.225
Show solution
The side is a quarter of the perimeter, 56 / 4 = 14 cm. The area is the side squared, 14 x 14 = 196. Find the side first; squaring the perimeter is the classic slip.
- Question 11Easy
Find the volume of a cylinder of radius 14 cm and height 15 cm (take π = 22/7).
- A.9240Correct
- B.11440
- C.7040
- D.8415
- E.10065
Show solution
Volume = πr²h = 22/7 × 14² × 15 = 9240 cubic cm.
- Question 12Easy
Find the volume of a cylinder of radius 21 cm and height 20 cm (take π = 22/7).
- A.31845
- B.28545
- C.26895
- D.27720Correct
- E.23595
