Regular and Irregular Figures
A figure bounded by line segments is a regular figure.
Figures bounded by curved lines are called irregular figures.
The space enclosed by the line segments is called the area of a figure.
For example:
Given below is a square bounded by four line segments each of length 1 cm.
The area of the square of sides 1 cm is 1 square cm (sq. cm) or centimetre2 (cm2)
What is the area of a square of sides 3 cm?
The above square consists of 9 small squares of area 1 sq.
cm each.
Therefore, the area of square ABCD is 9 sq.cm (cm2)
Note: Square cm or centimetre2 is the unit of area.
