Question:01

Write down the suitable measuring units for the following Quantity ( in Km,m, or cm)

(i) Length of a Pencil

(ii) Length of your Classroom Blackboard

(iii) Height of a person

(iv) Distance from your Home to School

(vi) Size of your study table

Solution:

(i) Most Suitable Measuring unit for “Length of a Pencil” is centimeter (cm).

(ii) Length of Your Classroom Blackboard can be measured in meter (m).

(iii) Height of a person measured in m.

(iv) Distance from your home to school is measured in Km.

(v) Height of your Classmates measures in m.

(vi) Size of your study table is also measured in m

Question:02

Convert Following Bigger Quantity into Smaller Ones

(i) 1Kg =

(ii) 5 Km =

(iii) 2 Litre =

(iv) 1 Metre =

(v) 1 hour =

(vi) 5 minutes =

Solution:

(i) 1 Kg =1000g              [1kg = 1000g]

(ii) 5 Km = 5000 m          [1Km=1000m]

(iii) 2 Litre =2000ml       [1 litre=1000ml]

(iv) 1 Metre = 100 cm      [1 Metre=100 cm ]

(v) 1 Hour = 60 minutes   [1 Hour= 60 Minutes]

(vi) 5 Minutes = 5 ×60 =300 seconds    [1 Minute = 60 seconds]

Question:03

Observe the given Figure carefully and Answer the Following Questions

(i) What is the distance between Lucknow and Agra

(ii) Write down the distance from Agra to Noida

(iii) Maximum Distance Between Two places

Solution:

See the given figure carefully to answer the following questions

(i) What is the distance between Lucknow and Agra

Solution:

The Distance between Lucknow and Agra is Sum of the Distance from” Lucknow → Kanpur→Agra “.

Dis(Lucknow to Agra) = Dis(Lucknow to Kanpur +Kanpur to Agra)

Note: Here “Dis” denote Distance Between two places

Lucknow to Agra  = 93 Km + 276 Km

Lucknow to Agra = 369 Km

(ii) Write down the distance from Agra to Noida

Solution:

Dis(Agra to Noida)=Dis(Agra to Mathura ) + Dis(Mathura to Noida)

=57 Km + 141 Km

=  198 Km

(iii) Maximum Distance Between Two places

Answer: Maximum Distance Between the Two places is from Kanpur to Agra which is 276 Km.

Question:04

Problem:01 If the Distance from Lucknow to Agra is 369 Km whereas the Distance between Agra and Mathura is 57 Km. Calculate the distance Between Lucknow and Mathura.

Solution:

It is given,

Distance from Lucknow to Agra is 369 Km.

Whereas Distance Between Agra to Mathura is 57 Km.

∴ Distance From Lucknow to Mathura = Lucknow→Agra + Agra → Mathura

= 369 Km + 57 Km

= 426 Km

Problem:02 Find the Length of the total Boundary of a Rectangular Garden whose Length is 20 m 25 cm and breadth 18 m 75cm.

Solution:

Length of the Rectangular Garden= 20 m 25 cm

Breadth of the Garden = 18 m 75 cm

∴ Total length of the Boundary given by = AB +BD + DC+CA

=20 m 25 cm + 18 m 75 cm + 20 m 25 cm + 18 m 75 cm

= 2(20 m 25 cm + 18 m 75 cm)

=2(38 m 100 cm)

= 76 m 200 cm

Hence , The total Length of the Rectangular Boundary = 76 m 200 cm
