Answer 2

Answer:

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.
