mokshitha14: why should we take 20 and 30

aaditvi: U can take any value...just for an example i took 20 and 30 at random

mokshitha14: Can I take 30 and 40 also

aaditvi: Yes u can take any value and chk your ans

mokshitha14: okay

mokshitha14: Thank u

aaditvi: Area = 30*40 = 1200
Area = 60*80 = 4800 (after 100% inc )
Inc in area = 4800-1200 = 3600
Inc % = (3600/1200)*100 = 300
