## Ans 8:

Class : Class 8
The answer should be A. Out of the 4 figures only the square has 2 lines of symmetry. The other figures like the parallelogram and the F have 0 lines of symmetry. The isosceles triangle has one line of symmetry. And the parallelogram has 0 lines on symmetry. On the vertical axis, when we divide it into 2 parts. 1 part is higher at the upper side and the second one is higher at the lower side. The same happens with the horizontal axis.

Subject :IMO    Class : Class 3

## Ans 1:

Class : Class 8
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 2:

Class : Class 10
Please use proper words. It is perimeter. Not total length. Total length is the sum of the two longer sides.

## Ans 3:

Class : Class 8
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

Class : Class 3

## Ans 5:

Class : Class 3
Both A and C are correct

## Ans 6:

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

Class : Class 8
Answer is d.

## Ans 8:

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 9:

Class : Class 4
Yes both A and C are Correct

## Ans 10:

Class : Class 4
A and C are Correct

Class : Class 3

## Ans 12:

Class : Class 2
both A and C are correct

## Ans 13:

Class : Class 7
A and C both are correct. it should be perimeter or boundary.

## Ans 14:

Class : Class 7
Please use the correct wordings, Perimeter. ItÃ¢Â€Â™s just confusing to deal with word length.

Class : Class 5
A

## Ans 16:

Class : Class 3
160 is the perimeter of the big rectangle and not the length

## Ans 17:

Class : Class 3
lenght should be replaced by parameter. ques.wording is wrong

## Ans 18:

Class : Class 3
160 is the perimeter not the length
