RS Aggarwal Solutions for Class 6 Maths Chapter 21 Concept of Perimeter and Area

This chapter explains the concept of "Concept-of-Perimeter-and-Area", the perimeter is the distance around the outside of a shape. The area measures the space inside a shape.


The area is the region bounded by the shape of an object. The space covered by the figure or any geometric shapes is the area of the shape. The area of all the shapes depends upon its dimensions and properties. Different shapes have different areas. The area of the square is different from the area of a kite.


The perimeter of a shape is defined as the total distance around the shape. It's the length of any shape if it is expanded in a linear form. The perimeter of different shapes can match in length with each other depending upon their dimensions.

For example, if a circle is made of a metal wire of length L, then the same wire we can use to construct a square, whose sides are equal in length.
