Area of rectangle

Area measures the surface of something

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.

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

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

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

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
