CHAPTER 4 : PERIMETER AND AREA

4.1 Perimeter

Perimeter is the sum of the lengths of all the sides of a figure. Thus perimeter is a measure of lengths. In case of a circle the perimeter means its circumference.

The two dimensional space enclosed by the perimeter is called area. Since it is a two-dimensional space, area is measured in square units like cm2 or square feet.
