Question
On a squared paper, draw any irregular closed figure. Find the approximate area by counting the number of squares complete, more than half and exactly half.
✓
Answer
Any irregular figure: This figure consists of $10$ complete squares, $1$ exactly half square, $7$ more than half squares and 6 less than half squares.
If we assume that the area of one complete square is $1\ cm^2$,
Then the area of this shape $= (10 + 1 \times 12 + 7 \times 1) = 17.5\ cm^2$
