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.
