Overview

In this chapter, we learn about two important measurements of plane shapes: perimeter and area. Perimeter is the total distance around a shape, while area is the amount of space inside it. These concepts help us solve real-life problems like finding how much wire is needed to fence a field or how mu

Key Concepts

Perimeter is the total length

Perimeter is the total length of the boundary of a closed figure. For a rectangle, it is calculated as 2 × (length + breadth). For a square, it is 4 ×

Area is the space enclosed within

Area is the space enclosed within a shape. For a rectangle, area = length × breadth. For a square, area = side × side. It is measured in square units

For irregular shapes

For irregular shapes, perimeter is the sum of all sides. Area can be estimated using graph paper by counting full and half-filled squares.

Real

Real-life problems involving cost of fencing, carpeting, or tiling use perimeter and area formulas. Units must be converted if different.
