length is 15 and breadth is 13. There was a silly mistake in it.

## Ans 4:

Class : Class 5
I thought that it's in a square shape...Ã¢Â€Â¦Ã¢Â€Â¦Ã¢Â€Â¦.that is why I did 15 X 15 not 15 X 13....

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 squareÃ¢Â€Â™s all sides are equal so itÃ¢Â€Â™s area should be = 15*15= 225 sq.cm .
