We can not say which figure has more area just be looking them. Thus to find area we use square paper
We ignore ‘less than half – filled squares’ and count ‘more than half-filled squares’ just as one square, then, sum of fully – filled and these is the estimated area of figure.
Area of china rose leaf = 25 sq. unit and
Area of pepal leaf = 15 sq. unit
Ratio of Area of china rose leaf to pepal leaf = 25 : 15 = 5 : 3
Thus, Area of china rose leaf is more.
