Question

Draw an irregular figure on graph paper and estimate its area.

Answer 1

Step 1:-Consider an irregular figure on a graph paper

Step 2:- If more than half of square is covered by leaf then it will be counted as 1 and less than that will be counted as 0

Step 3:- Now count the number of fully covered squares

So, Here 63 squares fully covered

Step 4:- Now count the more than half covered squares and each will count as 1 square

There are 17 questions which are more than half filled so, we can consider these as 17

Therefore, total area of this figure is $63+17=80$ square unit
