but that answer is 21%...but how...i can't understand.
If it is a square, it will increase by 21%
if you take a rectangle, it will increase by 10%
yeah... it's a square....so plz explain that...i know answer but I can't explain it...
area of a square of 10m sides is 100, if you increase the side by 10% ie.1m, area will be 11*12= 121. now the area increased by 21%
11*11=121
thanks...
