Perimeter and Area for Class 5

In this chapter, we will explore the concepts of perimeter and area, essential tools for understanding the space around us. This chapter will guide us through the fundamentals of measuring the boundary and the surface space of various shapes. By learning these concepts, we'll become wizards at figuring out how much space a shape covers and how long its edges are.

What is Perimeter?

Perimeter is the total distance around a two-dimensional object or the length of the boundary of a two-dimensional object.

Perimeter = Sum of all sides

Units of measurement for perimeter are centimetres (cm), metres (m), inches (in), feet (ft), etc.

What is Area?

Area is the space occupied by a two-dimensional object. It signifies the region enclosed within the boundary of a closed shape.

Area is measured in square units such as square centimetres (cm²) and square metres (m²).

Land areas are measured in acres and hectares.

1 acre = 100 m^{2
1 hectare = 10000 m2}
