We shall joint points on a graph paper to form different geometric figures and also try to find the space occupied by these figures.

We pasted the graph paper on a card board. We formed different geometrical figures on it by joining points and let's try to find the area enclosed by them.

Let's fill up the data and let's measure area:

Shapes	Number of complete small squares	Number of half small squares	Number of parts bigger than half square	Number of parts smaller than half square	Area (1 small square$=1\mathrm{Sqcm}$)
$1$

We pasted the graph paper on a cardboard. We formed different geometrical figures on it by joining points and let's try to find the area enclosed by them.

Let's fill up the data and let's measure area:

Calculate how much (in $\mathrm{Sqcm}$) area is occupied by my stamp.

Find the area (in sqcm)of the circular figure.

Find the area (in $\mathrm{Sqcm}$ ) of my figure in the image.

We find that the circular figure has occupied more than half portion of _____ squares. Hence, the area of this circular figure is approximately _____ $sq cm$.
