Thank u Sohan, your answer was very helpful :)

Ans 2:

Sohan R Jolapuri from Amanora School, Pune
Class : Class 5
Answer: C Explanation: Add all the numbers given their to find the length. It is 9+2+4=15 Unfold the napkin. you will get a number 9 at the left hand side with some space left. you will get a number 4 on the right hand side with some space left. if you imagine this or look at this carefully, you will notice that the space left at the either sides is actually 4 and 9 respctively. so, to find the breadth, add thesess no.-- 9+4=13. So l=151, b=13. Area is being asked. Formula of calculating area of a rectangle: lXb= 15 X 13 = 195 cm'2 Hence, option C is correct.

Answer should be Option B because in the solution the napkin unfolded looks like a square and a square’s all sides are equal so it’s area should be = 15*15= 225 sq.cm .

Ans 13:

Sohan R Jolapuri from Amanora School, Pune
