The area of the shapes like triangle, square etc., are found by standard formulae. But we can find the approximate area of shapes like leaves as follows.

**Area
of Irregular Shapes**

The area of the shapes like triangle, square etc.,
are found by standard formulae. But we can find the approximate area of shapes like
leaves as follows.

Place a leaf on a graph sheet and trace its boundary.
Now observe the squares of size 1 *cm* × 1 *cm* inside of this boundary. We get complete squares
(Green), partial but bigger than half squares (Orange) and half squares (Blue).
The smaller than half squares which have negligible area are omitted.

Now the approximate area of the leaf

= Number of full squares + Number of more than half squares + 1/2 × Number
of half squares

= (14 + 6
+ ½ × 2) *sq*. *cm*

= 21 *sq*. *cm*

**Note**

You will learn to find the actual
area of irregular shapes like leaves in your higher classes.
