Area of a rectangle is discussed here. We know, that a rectangle has length and breadth.

Let us look at the rectangle given below.

Each rectangle is made of squares. The side of each square is 1 cm long. The area of each square is 1 square centimeter.

Let us find the area of a rectangle having length 5 cm and breadth 4 cm.

From the above figure, it is clear that we can divide this rectangle into 20 squares of sides 1 cm each. SO, the area = 20 cm2

Thus the area of the rectangle = 5 cm × 4 cm

= 20 cm2

So when we multiply its length and breadth we get the area of the rectangle.

The rectangle ABCD has 8 such squares. Therefore, its area is 8 sq cm. Similarly we can find the areas of the other rectangles by counting the number of squares. We also note the length and breadth of each rectangle and write in the table below
