Ans 2:

both A and C are correct

Ans 3:

Varenyam Wadhwa from Hansraj Model School, Punjabi Bagh, New Delhi
Class : Class 3

Ans 4:

Samaira Ahuja from Gyanshree, Noida
Class : Class 3
160 is the perimeter of the big rectangle and not the length

Ans 5:

Rijrashwa Sreejith from Devamatha C M I Public School, Thrissur
Class : Class 4
Please use proper words. It is perimeter. Not total length. Total length is the sum of the two longer sides.

Ans 6:

inaira heredia from Jamnabai narsee international school, MUMBAI
Class : Class 5
Yes both A and C are Correct

Ans 7:

Rishaank Goel from Lotus valley , Noida
Class : Class 3
160 is the perimeter not the length

Ans 8:

ANSHUL TANWAR from ST TERESA CONVENT SCHOOL GHAZIABAD, NOIDA
Class : Class 3
lenght should be replaced by parameter. ques.wording is wrong

Ans 9:

Vedansh Deewan from Stemfield International School , Jabalpur
Class : Class 3
A should be correct???

Ans 10:

Akshara Dalan from DR D Y PATIL INTERNATIONAL SCHOOL NERUL, NAVI MUMBAI
Class : Class 3
The word should be PERIMETER as the word TOTAL LENGTH [mentioned] can mean the sum of the 2 sides of the rectangle and can not be understood very well.So, according to me the answer can be both A as well as C.

Ans 11:

Pragnay Priyadarshi from Quantum Leap School, HYDERABAD
Class : Class 7
Please use the correct wordings, Perimeter. It’s just confusing to deal with word length.

Ans 12:

Myra Srivastava from Manav Rachna International school , Gurgaon
Class : Class 3
Option is confusing. A rectangle length is not the same as rectangle perimeter...

Ans 13:

Eshan Ghosh from Don Dosco, Berhampore
Class : Class 3
Both A and C are correct

Ans 14:

Iraj Singh from DPS Megacity, Kolkata
Class : Class 9
The correct answer is D because the total length of the large rectangle is 160 meters and the total length of the small rectangle is 100 meters

Ans 15:

Vaishnavi singh from All saint international school , Alwar
Class : Class 5
A

Ans 16:

Rishaank Goel from Lotus valley , Noida
Class : Class 3

Ans 17:

Yash from Dps, Noida
Class : Class 2
sorry I was wrong the ans is d only because total length is here equal to perimeter for this condition

Ans 18:

RAGHAV VARSHNEY from CITY MONTESSORI SCHOOL GOMTINAGAR LUCKNOW, Lucknow
Class : Class 7
A and C both are correct. it should be perimeter or boundary.

Ans 19:

yuvaan PALIWAL from gyaananda school, gurugram
Class : Class 3

Ans 20:

yuvaan PALIWAL from gyaananda school, gurugram
Class : Class 3

Ans 21:

IAMLOST from ABC, Pune

A and C are correct.Please write unambiguous lines. Write boundary or perimeter to be precise.as children view rectangle in length and breadth only.

Ans 22:

Hiza Goel from MRIS-14, Faridabad
Class : Class 3
the wordings are not correct.. there is confusion with the word total length.. it means the length of the rectangle or the perimeter.. it is unclear.
