Measuring Length Class 4 Overview

Before we jump into the Class 4 Maths Chapter 6 Measuring Length question answer section, let’s look at the tools we use. This chapter is mostly on three units:

• Centimetre (cm): This is a unit of measurement for little things, like a needle or a cell phone.

• Metre (m): Used for bigger things like the length of a room or a saree.

• Kilometre (km): Used for really vast distances, such as the space between two cities.

Measuring Length Class 4 Maths Question Answer (NCERT Exercises)

The following section covers important exercises found in the textbook, including estimation and practical calculations.

1. Estimating Real-World Objects

In this chapter, students are asked to identify the best unit for different objects.

Question: For the things that are commonly measured in metres, put a tick mark (✓).

(a) Height of a student

(b) Length of a blackboard

(c) Thickness of a mobile phone

(d) Length of a classroom door

Answer: * (a) Height of a student (✓)

• (b) Length of a blackboard (✓)

• (d) Length of a classroom door (✓)

• Note: A mobile phone is too small for metres and is measured in centimetres.

2. Animals and Large Measurements

Comparing the sizes of animals is a great way to understand large lengths.

Question: A blue whale is about 30 metres long. A bus is about 15 metres long. How many buses would be equal to the length of two blue whales?

Solution:

• Length of one blue whale = 30 metres.

• Length of two blue whales = 30 + 30 = 60 metres.

• Length of one bus = 15 metres.

• Number of buses needed = 60 ÷ 15 = 4 buses.

3. Sports Meet: The Girls' Race

This problem helps students learn how to figure out how far apart things are on a track.

Question: Arundhati is 6 meters from the finish line in a 100-meter race. Rehana is three meters behind Arundhati. Rehana is 6 meters ahead of Konkana and Uma. How far away are Konkana and Uma from the end?

Answer: * Arundhati to Finish = 6m.

• Rehana to Finish = 6m + 3m = 9m.

• Konkana and Uma to Finish = 9m + 6m = 15 metres.

4. Running Around a Park

Devi Prasad runs around a park near her house to stay in shape.

Question: The park's edge is 400 meters long. How many laps does Devi Prasad need to run to finish 2 kilometres?

Solution:

• Goal distance = 2 km = 2000 metres (since 1 km = 1000m).

• Length of one round = 400 metres.

• Number of rounds = 2000 ÷ 400 = 5 rounds.

5. Comparing Height Records

We may see a list of records for the high jump and long jump. Let's see how to tell them apart.

Question: Chandra Pal’s high jump record is 2 metres 17 cm. Javier S. has the world record of 2 metres 45 cm. How many more cm does Chandra Pal need to jump to break the world record?

Solution:

• First, convert both to centimetres:

• World Record = 245 cm.

• Chandra Pal's Jump = 217 cm.

• Subtract the two: 245 - 217 = 28 cm.

• Chandra Pal needs to jump 28 cm more to match the world record.

6. The Long Path to School

Some students have to travel long distances to reach their school. This example helps you calculate total daily travel.

Question: Subodh goes to school from his house. He travels 400 meters to a pond, then 150 meters through the pond, then 350 meters over a verdant field and finally 100 meters to the gate. How far does he walk in total? Is it more than one kilometre?

Solution:

• Total Distance = 400m + 150m + 350m + 100m.

• 400 + 150 = 550.

• 550 + 350 = 900.

• 900 + 100 = 1000 metres.

• Since 1000 metres is exactly 1 kilometre, the distance is not more than 1 km; it is exactly 1 km.

7. Building Heights and Landmark Comparisons

We may learn about vertical height by looking at notable buildings.

Question: The Qutub Minar is 72 metres high. About how many metres high is your classroom? If one classroom is 3 metres high, how many such rooms stacked on top of each other would equal the Qutub Minar?

Solution:

• Height of Qutub Minar = 72 metres.

• Height of one classroom = 3 metres.

• Number of rooms = 72 ÷ 3 = 24 rooms.

• So, if you placed 24 classes on top of each other, they would be as tall as the Qutub Minar.

8. The Broken Scale Challenge

Our tools aren't always flawless. This chapter is all about how to measure with a broken scale.

Question: Varun has a broken scale that starts at 2 cm instead of 0 cm. He measures a pencil, and the end of the pencil reaches the 14 cm mark. What is the actual length of the pencil?

Answer: If the scale doesn't start at zero, you can get the length by subtracting the starting point from the end point.

• To figure it out: 14 cm - 2 cm = 12 cm.

• The pencil is really 12 cm long.
