CBSE Class 4 Maths Long And Short Worksheet Set 03

Competency Problem Solving Ability:

Question 1. Find the length of the boundary using a thread. Measure the length in cm scale
Answer: Place a thread carefully along the irregular closed boundary of the given figure, ensuring it covers the entire loop without overlapping. Mark the starting and ending points on the thread. Then, stretch the thread straight along a standard ruler starting from the zero mark to find the length in centimeters.
Let us measure the thread length.
Length = 12 cm
In simple words: Wrap a thread around the shape, then measure the straight thread on a ruler to find the boundary length.

Exam Tip: Always keep the thread aligned precisely along the boundary curve and ensure the ruler reading starts from zero.

Question 2. Construct line segments of the following length
a. 4cm
b. 2cm
Answer:
a. To construct a line segment of length 4 cm:
1. Mark a starting point, say \(A\), on a paper.
2. Place the zero mark of a ruler firmly at point \(A\).
3. Mark a second point, say \(B\), exactly at the 4 cm mark on the ruler.
4. Draw a straight line joining point \(A\) and point \(B\).
Length of line segment \(AB = 4\text{ cm}\).

b. To construct a line segment of length 2 cm:
1. Mark a starting point, say \(P\), on a paper.
2. Place the zero mark of a ruler firmly at point \(P\).
3. Mark a second point, say \(Q\), exactly at the 2 cm mark on the ruler.
4. Draw a straight line joining point \(P\) and point \(Q\).
Length of line segment \(PQ = 2\text{ cm}\).
In simple words: Draw a straight line from zero to the given centimeter mark using a ruler.

Exam Tip: Always use a sharp pencil and ensure the ruler does not slip while marking the endpoints.

Question 3. A hare and a tortoise are having a running race.
Who is near the finishing line? _________________
Answer: Tortoise
Total distance from the starting line to the finishing line = \(7\text{ m}\).
Distance of the hare from the finishing line = \(4\text{ m}\).
Distance of the tortoise from the finishing line = \(3\text{ m}\).
Since \(3\text{ m}\) is less than \(4\text{ m}\), the tortoise is closer to the finishing line.
In simple words: The tortoise has only 3 m left to reach the finish line, while the hare has 4 m left, so the tortoise is closer.

Exam Tip: Compare the remaining distances given in meters; the smaller distance value means closer proximity to the finish line.
