1. Area of rectangle

2. Area measures the surface of something

3. To find out how much shape is inside we can count the squares.
The area of a shape is the amount of space inside it.
The area of the shape is 18cm2.

4. Area of Rectangle Using formula
Length=4
Width=2 A B C D
The area of a rectangle is determined by
multiplying length x width.
4 x 2 = 8

5. Now the area of the rectangle = Total number of squares.
= Number of squares in 2 rows.
= 4 + 4
= 4 x 2
= (length x breadth) sq. units
Usually we denote length as ‘l’, breadth as ‘b’
Area of a rectangle = (l x b) sq. units

6. Example 1: Find the area of a rectangle whose length is 4 cm and breadth 8 cm Solution: Length=4cm, Breadth=8cm 8 4
Area of a rectangle = length x breadth
= 4 cm x 8 cm
= 32 sq. cm

7. Example 2: Find the area of a rectangle whose length is 5 cm and breadth 12 cm Solution: Length=5cm, Breadth=12cm 12 5
Area of a rectangle = length x breadth
= 5 cm x 12 cm
= 60 sq. cm
