BKSB Measurement and Area Questions and Answers 1 — Questions and Answers
Question 1: A landscaper is laying turf for a new rectangular lawn that measures 12 metres long and 5 metres wide. What is the total area of turf required to cover the lawn?
- 17 m²
- 60 m² (Correct answer)
- 34 m²
- 144 m²
Correct answer: 60 m²
The area of a rectangle is calculated by multiplying its length by its width. In this scenario, the calculation is 12 metres × 5 metres = 60 square metres (m²).
Question 2: A square room has a wall that is 4.5 metres long. What is the perimeter of the room?
- 20.25 m²
- 9 m
- 16 m
- 18 m (Correct answer)
Correct answer: 18 m
The perimeter is the total distance around a shape. Since a square has four equal sides, you calculate the perimeter by multiplying the length of one side by 4. The calculation is 4.5 metres × 4 = 18 metres.
Question 3: A project requires a piece of wood that is 1.5 metres long. Which of the following measurements is the same as 1.5 metres?
- 150 centimetres (Correct answer)
- 15 millimetres
- 1500 centimetres
- 0.15 centimetres
Correct answer: 150 centimetres
There are 100 centimetres in 1 metre. To convert metres to centimetres, you multiply the number of metres by 100. Therefore, 1.5 × 100 = 150 centimetres.
Question 4: A triangular flower bed has a base of 6 metres and a perpendicular height of 4 metres. What is the area of the flower bed?
- 24 m²
- 10 m²
- 12 m² (Correct answer)
- 20 m²
Correct answer: 12 m²
The formula for the area of a triangle is (base × height) / 2. For this flower bed, the calculation is (6 m × 4 m) / 2 = 24 / 2 = 12 square metres (m²).
Question 5: You need to find the volume of a packing box to see if an item will fit. The box measures 50 cm in length, 20 cm in width, and 30 cm in height. What is its volume?
- 100 cm³
- 30,000 cm³ (Correct answer)
- 1,500 cm³
- 3,000 cm³
Correct answer: 30,000 cm³
The volume of a cuboid (a box shape) is found by multiplying its length, width, and height. The calculation is 50 cm × 20 cm × 30 cm = 30,000 cubic centimetres (cm³).
Question 6: An L-shaped room is made of two joined rectangular sections. The larger section measures 4m by 5m, and the smaller section measures 2m by 3m. What is the total floor area of the room?
- 14 m²
- 32 m²
- 20 m²
- 26 m² (Correct answer)
Correct answer: 26 m²
To find the area of a composite shape like this, calculate the area of each individual rectangle and then add them together. Area of section 1 = 4m × 5m = 20 m². Area of section 2 = 2m × 3m = 6 m². Total area = 20 m² + 6 m² = 26 m².
