Area is the amount of space or surface covered by all the sides of that shape. We use ‘square’ as the basic unit of area.The area of a square of side 2m covers an area of 4 square metre or 4cm².similarly the area of a square with sides 3 centimetres long is 9 square centimetres or 9 cm².

Therefore,
Area of a square = L × L (or Side × Side)
Area of a rectangle=Length ×Breadth(that is L×B for short)

Examples1:
Find the area of a square with side 5cm.
Solution
Area of a square=Side×Side
Given a side=5cm
Area=5cm ×5cm
Area=25cm²

Example2
Find the area of a rectangle,if its length is 12cm and its breadth is 8cm.
Solution
Length= 12cm
