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

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

Length × Breadth
4 cm × 2 cm = 8 cm2
4 cm × 3 cm = 12 cm2
2 cm × 3 cm = 6 cm2
In each case we observe the length × breadth = Area of the rectangle.
Therefore, area of rectangle = length × breadth = l × b sq. units
From the above multiplication, we get the following facts:
Length of the rectangle = Area of the RectangleBreadth of the Rectangle
Breadth of the rectangle = Area of the RectangleLength of the Rectangle
