Class 4 Maths Word Problems Chapter 6 Measuring Length

Q1: A school is organizing a fun run, and they need to set up a rope along the running track. The first rope is 2 meters 50 centimeters long, and the second rope is 150 centimeters long. Which rope is longer, and by how much?

Sol:
Convert both to centimeters:
First rope = 2 meters 50 cm = 200 + 50 = 250 cm
Second rope = 150 cm
Subtract:
250 cm – 150 cm = 100 cm
The first rope is 100 cm longer.

Q2: Samantha has a pencil that is 18 cm long, and her friend James has a pen that is 22 cm long. By how many centimeters is James' pen longer than Samantha’s pencil?

James' pen is 4 cm longer.

Q3: At a park, a tree is 2 meters 20 centimeters tall, and a child is 1 meter 75 centimeters tall. How much taller is the tree compared to the child?

Sol:
Convert both to centimeters:
Tree = 2 meters 20 cm = 200 + 20 = 220 cm
Child = 1 meter 75 cm = 100 + 75 = 175 cm
Subtract:
220 cm – 175 cm = 45 cm
The tree is 45 cm taller.

Q4: If a ribbon is 125 cm long and a tailor decides to cut it into 5 equal pieces, how long will each piece be?

The perimeter is 400 cm.

Q6: In a community garden, the length of a plot is 15 meters and the width is 10 meters. What is the area of the garden?
