CBSE Class 4 Mathematics Measuring Length MCQs Set 01

Answer: [D] 4

Explanation:
1. A quarter means one part out of four equal parts.
2. If we divide 1 meter into four equal parts, each part is a quarter meter.
3. So, we need 4 quarter meters to make 1 whole meter.

Answer: (C) 1 m 52 cm

Explanation:
1. Gaurav's height is 92 cm.
2. His brother is 60 cm taller, so we add 92 cm and 60 cm.
3. 92 + 60 = 152 cm.
4. We know that 100 cm makes 1 meter, so 152 cm is equal to 1 m and 52 cm.

Answer: [A] Scale/measuring tape

Explanation:
1. An eraser is a small object.
2. We measure small things in centimetres or millimetres.
3. A standard school scale or measuring tape is the best tool for this.

Answer: [B] 1 cm

Explanation:
1. A standard measuring tape has marked sections.
2. In this lesson, each red bar is used to show a length of exactly 1 cm.
3. So, each red bar represents 1 centimetre.

Answer: (B) Centimetre

Explanation:
1. A rice grain is very tiny.
2. We can measure its length using centimetres, which are marked on our school rulers.
3. According to the worksheet, centimetres is selected as the correct choice.

Answer: (B) m

Explanation:
1. A classroom is not too big like a town, and not too small like a pencil.
2. Kilometres (km) are too big and centimetres (cm) are too small.
3. Therefore, we use metres (m) to measure the size of a room.

Answer: [D] 5

Explanation:
1. The total length of the whale is 30 metres.
2. Each bus is 6 metres long.
3. To find how many buses we need, we divide 30 by 6.
4. 30 divided by 6 is 5, so we need 5 buses.

Answer: (C) Ruler

Explanation:
1. A weighing machine is for weight.
2. A clock is for time, and a thermometer is for temperature.
3. We use a ruler to find how long or short an object is.

Answer: [A] Weight

Explanation:
1. Depth, width, and height all tell us about how long, deep, or tall something is.
2. Weight tells us how heavy something is.
3. So, weight is not a measurement of length.

Answer: (B) 10 cm

Explanation:
1. There is a small typo in the original question sheet which says '100m'. It should be '100 mm'.
2. 10 millimetres (mm) make 1 centimetre (cm).
3. So, to convert 100 mm to cm, we divide 100 by 10.
4. 100 divided by 10 is 10, which gives us 10 cm.

Answer: [B] Length of the boundary of an object

Explanation:
1. The perimeter is the total path around the outside of a shape.
2. You can find it by adding the lengths of all outer sides.
3. This means it is the total length of the shape's boundary.

Answer: [B] The length of each red bar on the measuring tape

Explanation:
1. In the textbook chapter, they use a measuring tape with red bars.
2. They define 1 cm as the length of one of these red bars.
3. This helps kids visualize how long 1 centimetre is.

Answer: (B) 540 cm

Explanation:
1. We know that 1 metre is equal to 100 centimetres.
2. So, 5 metres is equal to 5 times 100, which is 500 centimetres.
3. Adding the extra 40 centimetres: 500 + 40 = 540 centimetres.

Answer: [B] Blue whale

Explanation:
1. A crocodile and ostrich are much smaller than 30 metres.
2. A normal bus is only about 12 metres long.
3. A blue whale is the largest animal and can grow up to 30 metres long.

Answer: (B) 100

Explanation:
1. One metre is a larger unit than one centimetre.
2. Exactly 100 centimetres fit inside 1 metre.
3. So, to turn metres into centimetres, we multiply the number of metres by 100.

Answer: [C] 50 cm

Explanation:
1. One whole metre is equal to 100 centimetres.
2. "1/2 metre" means half of one metre.
3. Half of 100 centimetres is 50 centimetres.

Answer: (A) Metre

Explanation:
1. A standard unit is the same for everyone in the world.
2. Cubit, handspan, and foot span change from person to person because hand and foot sizes are different.
3. A metre is a fixed, standard unit that never changes.

Answer: [C] 3 m

Explanation:
1. An ostrich is a very tall bird.
2. An adult ostrich usually grows to be about 3 metres tall.
3. So, 3 m is the correct answer.

Answer: (C) Centimetre

Explanation:
1. Handspan, footstep, and cubit are non-standard because different people have different sizes of hands and feet.
2. A centimetre is exactly the same length on every ruler everywhere.
3. Thus, centimetre is a standard unit of measurement.

Answer: (B) 10

Explanation:
1. First, convert the 2-metre board into centimetres: 2 m = 200 cm.
2. Each sticker is 20 cm long.
3. To cover the 200 cm board, we divide 200 by 20.
4. 200 divided by 20 is 10, so we need 10 stickers.

Answer: [B] 25 cm

Explanation:
1. One whole meter is equal to 100 centimetres.
2. "1/4 meter" means one-quarter of a meter (dividing it into four equal parts).
3. 100 divided by 4 is 25, so 1/4 meter equals 25 cm.

Answer: [C]. 100 centimetres

Explanation:
1. A metre is a standard unit used to measure longer distances.
2. In the metric system, exactly 100 centimetres make up 1 metre.
3. Therefore, 1 metre is equal to 100 centimetres.

Answer: (A) 20 cm

Explanation:
1. A square has four sides, and all four sides are equal in length.
2. If one side is 5 cm, then all four sides are 5 cm.
3. The perimeter (boundary) is the sum of all four sides: 5 + 5 + 5 + 5 = 20 cm.

Answer: (D) School → Market → Home

Explanation:
1. Let's compare the distances: 5 km, 2 km, 1 km, and 900 m.
2. Remember that 1 km is equal to 1000 m.
3. Since 900 m is less than 1000 m (1 km), 900 m is the shortest distance.
4. Therefore, the Market route is the shortest.

Answer: [D]. 600 cm

Explanation:
1. Since 1 m = 100 cm, then 2 m = 200 cm.
2. To find what 6 m is, we multiply 6 by 100 cm.
3. 6 times 100 is 600, so 6 m equals 600 cm.

Answer: (C) 455 cm

Explanation:
1. First, convert 4 metres into centimetres: 4 m = 400 cm.
2. Next, add the 55 cm: 400 cm + 55 cm = 455 cm.
3. So, the correct option is (C).

Answer: [C]. Metres

Explanation:
1. A classroom height is a fairly large distance but not as huge as a road between cities.
2. Measuring it in centimetres or millimetres would give us very big numbers.
3. Measuring in kilometres is for long distances.
4. Therefore, metres is the best and most appropriate unit to use.

Answer: [C]. Both are correct

Explanation:
1. Ramu says 120 cm. Shamu says 1 m 20 cm.
2. We know that 1 m is the same as 100 cm.
3. So, 1 m 20 cm is 100 cm + 20 cm, which equals 120 cm.
4. Since 120 cm is equal to 1 m 20 cm, both Ramu and Shamu are correct.

Answer: (A) 876 cm

Explanation:
1. Convert 8 metres to centimetres: 8 m = 800 cm.
2. Add the remaining 76 cm to it: 800 + 76 = 876 cm.
3. Thus, 8 m 76 cm is equal to 876 cm.
