Answer:
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:
Rectangle
ABCD
LMNO
PQRS
Area
8 sq. cm
12 sq. cm
6 sq. cm
Length
4 cm
4 cm
2 cm
Breadth
2 cm
3 cm
3 cm
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
