Observe the figures given below.

(a) (b)

Which figure has more area?
This can be done by placing them on squared paper or graph paper where every square has 1 cm ´ 1 cm
dimensions. The area is the number of cm squares covered by the figure on the squared paper. Before we
proceed we must remember the following points:

1. The area of one full square is taken to be 1 sq. unit.
1
2. The area of exactly half square is taken to be sq. unit.
2
3. The area of squares less than half are taken as 0.

4. The area of squares more than half are taken as 1 sq. unit.
EXAMPLE 1. Find the area of the figure given below:

SOLUTION : Let us count the number of squares:
Number of full squares = 10
Number of half squares = 0

Number of squares more than half = 2
Number of squares less than half = 4
1
1
Thus, total area covered is 10 ´ + 2 ´ + 4 0´ = 10 + 1 11 sq. cm.
=
2
EXAMPLE 2. Find the area of the figure given below:
SOLUTION : Let us count the number of squares:
Number of full squares = 10

Number of half squares = 0
Number of squares more than half = 2

Number of squares less than half = 4
